16 Psyche is a very big Main belt asteroid, well over 200 kilometers in diameter, and likely the biggest of the metallic M-type asteroids. It is estimated to have 0.6 percent of the mass of the entire asteroid belt.
This asteroid was found by Annibale de Gasparis on March 17, 1852 from Naples and named after the Greek nymph Psyche. The first fifteen asteroids to be found were given symbols by astronomers as a type of short-hand notation. In 1851, however, J. F. Encke suggested using a circled number. 16 Psyche was the first new asteroid to be found that was designated with this scheme (in 1852 by J. Ferguson).
Radar
observations indicate that it is made of iron-nickel. Psyche appears to be a case of an exposed metallic core from a bigger differentiated parent body. Unlike some other M-type asteroids, Psyche shows no sign of the presence of water or water-bearing minerals on its surface, consistent with its interpretation as a metallic body. Small amounts of pyroxene appear to be present.
If Psyche is the core remnant of a bigger parent body, we might expect other asteroids on similar orbits. Psyche does not belong to any asteroid family. One theory is that the collision occurred very early in the solar system's history, and all the other remnants have since been ground into fragments by subsequent collisions or had their orbits perturbed beyond recognition.
Psyche is massive enough that its perturbations on other asteroids can be measured, which enables a mass measurement. Its density is fairly low for metal (although fairly common for asteroids as such), indicating a fairly high porosity of 30–40%.
Psyche appears to have a fairly round surface and is approximately ellipsoidal in shape. Recent lightcurve analysis indicates that its pole points towards either ecliptic coordinates (β, λ) = (-9°, 35°) or (β, λ) = (-2°, 215°) with a 10° uncertainty. This gives an axial tilt of 95°.
Two stellar occultations by Psyche have been seen (from Mexico on March 22, 2002, and another on May 16, 2002). Lightcurve changes indicate a non-spherical body, consistent with the lightcurve and radar results.
Cancún
Cancún (pronounced as ) is a coastal city in Mexico's easternmost state, Quintana Roo, on the Yucatán Peninsula. About 573,000 people live in Cancún, but over 4,000,000 tourists visit Cancún every year on vacation. At present it is, with Acapulco, the Mexican resort best known in the world.
The resort is entirely artificial: few lived here before 1970. The first hotels were funded by the government. February to May is wonderful weather most of the time, and there are stunning white sand beaches. Even the sea is warm. There is now an airport, and bus connections to the rest of the Yucatán. The Yucatán has many Mayan sites, and some villages which are still mostly Mayan.
Norman, Oklahoma
Norman, is the county seat and largest city in Cleveland County in the U.S. state of Oklahoma. It is part of the Oklahoma City Metropolitan Statistical Area. Norman is about 20 miles south of Oklahoma City. James Garner and Toby Keith are from Norman. The University of Oklahoma is in Norman. Norman was founded in 1889 by Abner Norman. In 2008, "Money Magazine" said Norman was a very good place to live. Norman has one small airport and a railroad station.
Mid-Atlantic States
The Mid-Atlantic States (also called "Middle Atlantic States" or simply "Middle East") form one of the nine geographic divisions within the United States that are officially recognized by the United States Census Bureau. The division consists of three states: New Jersey, New York, and Pennsylvania. This definition corresponds with the region's traditional definition as the section of the Atlantic Seaboard between New England and the South. However, many people consider the Mid-Atlantic to be the states south of the Northeast, centered in Delaware, Maryland.
The traditional Mid-Atlantic States comprise the most densely-populated of the nine U.S. regions, and anchor the megalopolis which runs from Boston to Washington, D.C.. The southeastern part of New York State, eastern Pennsylvania, and all of New Jersey combine to form the bulk of the "moral region" of the Metropolis, according to socio-political geographers James Patterson and Peter Kim, co-authors of the 1991 book "The Day America Told The Truth". (Metropolis begins in the southern Connecticut suburbs of New York City and stretches along the Eastern seaboard to the northern Virginia suburbs of Washington, D.C.). The book classifies the remainder of New York State and Pennsylvania in the Rust Belt.
Landfall (meteorology)
Landfall is when a tropical cyclone or waterspout moves from being over water to being over land. When a tornadic waterspout makes landfall it can be called a tornado, and can cause damage to buildings and other things made by people. When a fair weather waterspout makes landfall it quickly spreads out and loses its energy; the water falls as rain.
A tropical cyclone is said to make landfall when its center moves over land; in tropical cyclones this can be when the eye moves over land. This is where most of the damage occurs because when the storm is over water there is a little chance of damage, except if the parts of the storm that are raining are over land, which can cause severe flooding especially when the system is moving slowly or not at all. The effects of landfall are:
Together with the high surf, these can cause a lot of beach erosion. In low lying areas the storm surge can stay inland for a long time and mix with chemicals already in the area to create a toxic mess. When a tropical cyclone makes landfall, the eye "closes", surf gets less, and winds get less as the cyclone spreads out, losing energy. Damage inland may include flooding rains, gusty winds, and severe weather associated with the cyclone's remnant thunderstorms.
A "landfall" should not be confused with a "direct hit", which happens when the core of high winds (or eyewall) comes over the land but the center of the storm stays over water. The effects of this are similar but storm surges can be much less. These effects are:
Freeport, Texas
Freeport is a city in Brazoria County, Texas within the Houston – Sugar Land – Baytown Metropolitan Area in Southeast Texas. As of the 2000 U.S. census, the city population was 12,708. Freeport is about sixteen miles from Angleton.
Dow Chemical is the major employer in Freeport, as the company operates a large chemical plant complex in Freeport.
San Luis Pass
San Luis Pass is a strait of water at the south-western end of Galveston Island off the shores of the U.S. state of Texas. It connects the sheltered waters of West Bay to the open Gulf of Mexico.
There are also two mountain passes of the same name in the USA:

Lincoln often refers to Abraham Lincoln, the 16th President of the United States. It may also mean:

19 Fortuna
19 Fortuna is one of the biggest main belt asteroids. It is made up of stuff similar to 1 Ceres: a darkly colored surface that is heavily space weathered and made up of primitive organic compounds, including tholins.
Fortuna is 225 km in diameter and has one of the darkest known geometric albedos for an asteroid over 150 km in diameter. Its albedo has been measured at 0.028 and 0.037.
The Hubble Space Telescope saw Fortuna in 1993. It was resolved with an apparent diameter of 0.20 arcseconds (4.5 pixels in the Planetary Camera) and its shape was found to be nearly spherical. Moons were searched for but none were detected.
Stellar occultations by Fortuna have been seen several times.
It was found by J. R. Hind on August 22, 1852 and named after Fortuna, the Roman goddess of luck.
20 Massalia
20 Massalia is a big and fairly bright Main belt asteroid. It is also the biggest member of the Massalia family of asteroids.
