A Resident Space Object (RSO) is a natural or artificial object that orbits another body e.g. Sun Orbiting, Earth Orbiting, Mars Orbiting etc.
 It is most often used to reference objects that are Earth orbiting.
 In the case of Earth orbiting the possible orbit classifications for an object are: Low Earth orbit (LEO), Medium Earth orbit (MEO), High Earth orbit (HEO) or Geosynchronous Earth orbit (GEO).
The TW Hydrae association is a group of approximately thirty very young stars located 50 parsecs from Earth that share a common motion and appear to all be roughly the same age, 5-10 million years old.
 The best studied members of this stellar association are TW Hydrae (nearest known accreting T Tauri star to the Earth), HR 4796 (an A-type star with resolved dusty debris disk; the most massive known group member), HD 98800 (a quadruple star system with debris disk), and 2M1207 (accreting brown dwarf with remarkable planetary-mass companion 2M1207b).
Beta Pictoris b (also abbreviated as β Pic b) is an exoplanet orbiting the young debris disk A-type main sequence star Beta Pictoris located approximately 63 light-years (19.4 parsecs, or nearly km) away from Earth in the constellation of Pictor.
 It has a mass around 7 Jupiter masses and a radius around 65% larger than Jupiter's.
 It orbits at 9 AU from Beta Pictoris (close to the plane of the debris disk orbiting the star) with a low eccentricity and a period of 20–21 years, and is the only known planet in the Beta Pictoris system.
The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation.
 Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy.
 The HST is named after the astronomer Edwin Hubble, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
A debris disk is a circumstellar disk of dust and debris in orbit around a star.
 Sometimes these disks contain prominent rings, as seen in the image of Fomalhaut on the right.
 Debris disks have been found around both mature and young stars, as well as at least one debris disk in orbit around an evolved neutron star.
 Younger debris disks can constitute a phase in the formation of a planetary system following the protoplanetary disk phase, when terrestrial planets may finish growing.
 They can also be produced and maintained as the remnants of collisions between planetesimals, otherwise known as asteroids and comets.
Apollo 8, the second human spaceflight mission in the United States Apollo space program, was launched on December 21, 1968, and became the first crewed spacecraft to leave Earth orbit, reach the Earth's Moon, orbit it and return safely to Earth.
 The three-astronaut crew — Commander Frank Borman, Command Module Pilot James Lovell, and Lunar Module Pilot William Anders — became the first humans to: travel beyond low Earth orbit; escape Earth's gravity; see Earth as a whole planet; enter the gravity well of another celestial body (Earth's moon); orbit another celestial body (Earth's moon); directly see the far side of the Moon with their own eyes; witness an Earthrise; escape the gravity of another celestial body (Earth's moon); and re-enter the gravitational well of Earth.
 The 1968 mission, the third flight of the Saturn V rocket and that rocket's first crewed launch, was also the first human spaceflight launch from the Kennedy Space Center, Florida, located adjacent to Cape Canaveral Air Force Station.
The beta angle (formula_1) is a measurement that is used most notably in spaceflight.
 The beta angle determines the percentage of time an object such as a spacecraft in low Earth orbit (LEO) spends in direct sunlight, absorbing solar energy.
 Beta angle is defined as the angle between the orbital plane of the spacecraft and the vector to the sun (i.e., which direction the Sun is shining from).
 The beta angle is the smaller angle (there are two angles) between the Sun vector (where the Sun is shining from in the sky) and the plane of the object's orbit.
 Note that the beta angle does not define a unique orbit plane; all satellites in orbit with a given beta angle at a given altitude have the same exposure to the Sun, even though they may be orbiting in completely different planes around the Earth.
 The beta angle varies between +90° and −90°, and the direction the satellite revolves around the body it orbits determines whether the beta angle sign is positive or negative.
 An imaginary observer standing on the Sun defines a beta angle as positive if the satellite in question orbits in a counter clockwise direction and negative if it revolves clockwise.
 The maximum amount of time that a satellite in a normal low Earth orbit mission can spend in the Earth's shadow occurs at a beta angle of zero.
 In such an orbit, the satellite is in sunlight no more than 59% of the time.
The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit.
 Its first component launched into orbit in 1998, and the ISS is now the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth.
 The ISS consists of pressurised modules, external trusses, solar arrays, and other components.
 ISS components have been launched by Russian Proton and Soyuz rockets, and American Space Shuttles.
HD 92945 is a K-type main sequence star in the constellation of Hydra.
 Its apparent visual magnitude varies by 0.02 magnitudes and is approximately 7.72 at maximum brightness.
 A debris disk has been observed around the star by coronagraphic imaging, using the ACS and NICMOS instruments on the Hubble Space Telescope.
 It appears to extend 45 to 175 astronomical units from HD 92945 and is inclined at approximately 29 degrees.
The Kessler syndrome (also called the Kessler effect, collisional cascading or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low earth orbit (LEO) is high enough that collisions between objects could cause a cascade where each collision generates space debris that increases the likelihood of further collisions.
 One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges infeasible for many generations.
