In Europe and Australia, the system was released to two separate marketing regions. One region consisted of most of mainland Europe (excluding Italy), and distribution there was handled by a number of different companies, with Nintendo responsible for most cartridge releases. Most of this region saw a 1986 release. Mattel handled distribution for the other region, consisting of the United Kingdom, Ireland, Canada, Italy, Australia and New Zealand, starting the following year. Not until the 1990s did Nintendo's newly created European branch direct distribution throughout Europe.

The HyperScan is a video game console from the toy company Mattel. It uses radio frequency identification (RFID) along with traditional video game technology. The included game was rated "T" (Teen, not suitable for under age 13) and the remaining titles were rated "E10+" (not suitable for under age 10) by the ESRB. Despite this, it was marketed toward boys between the ages of five and nine who were not ready for high-end video games in terms of maturity and/or expense. The console used UDF format CD-ROMs. The HyperScan has two controller ports, as well as a 13.56 MHz RFID scanner that reads and writes to the "cards" which, in turn, activate features in and save data from the game. Players are able to enhance the abilities of their characters by scanning cards. Games retailed for $19.99 and the console itself for $69.99 at launch, but at the end of its very short lifespan, prices of the system were down to $9.99, the games $1.99, and booster packs $0.99.

The Intellivision is a home video game console released by Mattel Electronics in 1979. The name "Intellivision" is a portmanteau of "intelligent television". Development of the console began in 1977, the same year as the introduction of its main competitor, the Atari 2600. In 1984 Mattel sold their video game assets to a former Mattel Electronics executive and investors that would become INTV Corporation. Games development started in 1978 and continued until 1990 when the Intellivision was discontinued. From 1980 to 1983 over 3 million Intellivision units were sold.

Max Steel is a line of action figures produced and owned by the toy company Mattel since 1999. The original figures based on the first TV series were similar to the original 12-inch G.I. Joe toys, consisting almost entirely of different versions of Max Steel, the main character, and one or two of his enemies, a couple of vehicles and two or three special packages. The original toy series ran from 1999–2012. At the end of that period, was substituted by a different series of toys with the same brand name, but with a change in quality and design intended to tie into the companion TV series in 2013. The 2013 line did not exhibit 1/6 scale of the original and reduced the number of articulations and action features of the figures.

In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing - by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense. Gravity assistance can be used to accelerate a spacecraft, that is, to increase or decrease its speed or redirect its path. The ``assist ''is provided by the motion of the gravitating body as it pulls on the spacecraft. The gravity assist maneuver was first used in 1959 when the Soviet probe Luna 3 photographed the far side of Earth's Moon and it was used by interplanetary probes from Mariner 10 onwards, including the two Voyager probes' notable flybys of Jupiter and Saturn.
For a decade from 1963 to about 1973, a substantial number of astronomers accepted a claim by Peter van de Kamp that he had detected, by using astrometry, a perturbation in the proper motion of Barnard's Star consistent with its having one or more planets comparable in mass with Jupiter. Van de Kamp had been observing the star from 1938, attempting, with colleagues at the Sproul Observatory at Swarthmore College, to find minuscule variations of one micrometre in its position on photographic plates consistent with orbital perturbations that would indicate a planetary companion; this involved as many as ten people averaging their results in looking at plates, to avoid systemic individual errors. Van de Kamp's initial suggestion was a planet having about 1.6 MJ at a distance of 4.4 AU in a slightly eccentric orbit, and these measurements were apparently refined in a 1969 paper. Later that year, Van de Kamp suggested that there were two planets of 1.1 and 0.8 MJ.

Question: What spacecraft used the gravitational pull of the planet to whose mass the other planets were comparable?
Answer: Voyager probes

The distance from Earth to the Sun is 1 astronomical unit (150,000,000 km), or AU. For comparison, the radius of the Sun is 0.0047 AU (700,000 km). Thus, the Sun occupies 0.00001% (10%) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly one millionth (10) that of the Sun. Jupiter, the largest planet, is 5.2 astronomical units (780,000,000 km) from the Sun and has a radius of 71,000 km (0.00047 AU), whereas the most distant planet, Neptune, is 30 AU (4.5 × 10 km) from the Sun.

Jupiter has been called the Solar System's vacuum cleaner, because of its immense gravity well and location near the inner Solar System. It receives the most frequent comet impacts of the Solar System's planets. It was thought that the planet served to partially shield the inner system from cometary bombardment. However, recent computer simulations suggest that Jupiter does not cause a net decrease in the number of comets that pass through the inner Solar System, as its gravity perturbs their orbits inward roughly as often as it accretes or ejects them. This topic remains controversial among scientists, as some think it draws comets towards Earth from the Kuiper belt while others think that Jupiter protects Earth from the alleged Oort cloud. Jupiter experiences about 200 times more asteroid and comet impacts than Earth.A 1997 survey of early astronomical records and drawings suggested that a certain dark surface feature discovered by astronomer Giovanni Cassini in 1690 may have been an impact scar. The survey initially produced eight more candidate sites as potential impact observations that he and others had recorded between 1664 and 1839. It was later determined, however, that these candidate sites had little or no possibility of being the results of the proposed impacts.More recent discoveries include the following:

The Great Red Spot is a persistent high - pressure region in the atmosphere of Jupiter, producing an anticyclonic storm 22 ° south of the planet's equator. It has been continuously observed for 188 years, since 1830. Earlier observations from 1665 to 1713 are believed to be of the same storm; if this is correct, it has existed for at least 350 years. Such storms are not uncommon within the turbulent atmospheres of gas giants.

American Tax Funding (ATF) is a private company based in Jupiter, Florida that engages in the purchasing and servicing of delinquent municipal real estate tax lien sales. Originally formed in 1997 as Transamerica Municipal Finance (TMF), a division of Transamerica Corporation. In August 2000 the founders completed a form of a management buyout of TMF, creating ATF. ATF currently buys and services real estate tax liens in over 14 states and has provided over $1 billion in relief to local governments. Many ATF tax liens are secured by either Wells Fargo Foot Hill or the Harris Nesbitt Corporation. The process of privatizing the municipal tax foreclosures process and outsourcing to out of state third party, for-profit, private companies has drawn criticism from housing advocates who argue that a for-profit tax foreclosure process leads to more foreclosures, displacement and vacancy. The other argument is that third party purchases of tax liens enables local governments to pay for essential services such as salaries for teachers, health care, police officers and firefighters. To date, no study has shown that the sale of tax liens to third parties leads to any increase in foreclosure activity. In fact, the sale of liens to third party purchasers often extends redemption periods and allows flexible repayment agreements for delinquent tax payers.

Question: What spacecraft used the gravitational pull of the planet for which the headquarters city of American Tax Funding is named?
Answer: Voyager probes
A molecular form called protonated molecular hydrogen (H+
3) is found in the interstellar medium, where it is generated by ionization of molecular hydrogen from cosmic rays. This charged ion has also been observed in the upper atmosphere of the planet Jupiter. The ion is relatively stable in the environment of outer space due to the low temperature and density. H+
3 is one of the most abundant ions in the Universe, and it plays a notable role in the chemistry of the interstellar medium. Neutral triatomic hydrogen H3 can only exist in an excited form and is unstable. By contrast, the positive hydrogen molecular ion (H+
2) is a rare molecule in the universe.

As with the majority of extrasolar planet discoveries so far, it was found by detecting small variations in the radial velocity of the star it orbits, caused by the tug of its gravity. A study of the radial velocity of HD 217107 carried out in 1998 revealed that its motion along the line of sight varied over a 7.1 day cycle. The period and amplitude of this variation indicated that it was caused by a planetary companion in orbit around the star, with a minimum mass slightly greater than that of Jupiter. The planet's mean distance from the star is less than one fifth of Mercury's distance from the Sun.

Question: What spacecraft used the gravitational pull of the planet the minimum mass was a little bit bigger than?
Answer: Voyager probes
Known officially as L'International des Feux Loto - Québec, the Montreal Fireworks Festival is the most prestigious and largest fireworks competition in the world. It is an annual international competition held in Montreal, Quebec, Canada since 1985. The event begins in June and carries on until August. Each summer, several pyrotechnical companies from different countries present a 30 - minute - long pyromusical show. Gold, Silver and Bronze Jupiter trophies are awarded to the winners. The Jupiters have become symbols of prestige within the fireworks industry. See the festival's. The fireworks are synchronized to music which is also broadcast over a local radio station. Over 3 million spectators gather each year to see the fireworks. The main viewing locations are: the Jacques - Cartier Bridge (closed to traffic the evening of each event), La Ronde (amusement park), and on either side of the St. Lawrence River. Approximately 6,000 fireworks are set off during each show.
