 Asteroid - Network Live
Asteroid naming is not always a free-for-all: there are some types of asteroid for which rules have developed about the sources of names.
Until the age of space travel, asteroids were merely pinpricks of light in even the largest telescopes and their shapes and terrain remained a mystery.
Asteroids are rocky and metallic objects that orbit the Sun but are too small to be considered planets.

 2004 FH - Wikipedia, the free encyclopedia
The asteroid will not make another close approach to Earth until 2044 when it will be no closer than 1.4 Gm (1.4 million kilometres).
2004 FH is an Aten family asteroid, although by some definitions it should be called a meteoroid, since it is smaller than 50 metres in diameter.
Despite its relatively small size (about 30 metres), it is still the third largest asteroid detected coming closer to the Earth than the Moon.

The value for y-velocity that caused the asteroid to come closest to Mars' orbit without actually crossing it on the first orbit was -4.555.
The output I receive is the positions of the bodies and the number of frames it took for the asteroid to cross Mars' orbit.
I also had some trouble in determining when the asteroids' orbit actually crossed Mars' orbit and when it was just touching it.

 1566 Icarus - Wikipedia, the free encyclopedia
Icarus features in Kim Stanley Robinson 's novel The Memory of Whiteness, in which the asteroid is inhabited by a religious cult that worships its close approaches to the Sun.
Icarus is the setting for Arthur C. Clarke 's short-story Summertime on Icarus (aka 'Icarus Ascending'), where an astronaut is stranded on the asteroid as it approaches perihelion.
1566 Icarus is an Apollo asteroid (a sub-class of

 Micah Reese
Since the orbit of the asteroid is mostly changed by a close pass with Earth, the probability of becoming a Mars-crosser increases with the probability of passing close to Earth.
In both cases, traces on the asteroid and Mars were used to help determine when the asteroid became a Mars-crosser.
This system was modeled using the velocities, positions, and masses of the planets and the asteroid as well as the law of Gravitation.

 69230 Hermes - Iridis Encyclopedia
Hermes is an S-class asteroid, and radar observations showed it to be a binary asteroid with two equal-sized components almost in contact with one another.
In October 2003, Brian A. Skiff of the LONEOS project made an asteroid observation that, when the orbit was calculated backwards in time, turned out to be a rediscovery of Hermes.
At the time, this was the closest known approach of an asteroid to the Earth.

 Science News: Radar reveals an asteroid's strange shape
Of the 56 asteroids he has studied by radar during the past decade, 23 are Earth-crossers--including three or four whose radar signatures, though not as detailed as those of 1989 PB, at least suggest concavities that could signify large craters or other low spots, he says.
"Probably sometime within the last 100 million years," says Ostro, noting that the orbits of most "Earth-crosser" asteroids probably evolved no longer ago than that, "there was a big, violent collision between objects in the main asteroid belt [lying between the orbits of Mars and Jupiter].
Analysis of the asteroid's shape should "let us make some statements about how tightly gravity is holding the two lobes together and begin to formulate theories about how it was formed," Ostro says.

 BBC - Stardate - Asteroids: History of Asteroid Hunting
Asteroid 4205, a Mars crosser, is named David Hughes in his honour.
As the nineteenth century progressed many more asteroids were discovered as the introduction of larger telescopes and the use of photography enabled fainter and fainter (and therefore smaller and smaller) asteroids to be found.
As the new asteroid moved through its orbit during the month it was heading towards the point of being directly behind the Sun (from the perspective of the Earthbound astronomers).

 metAMORphosis: Conscious Evolution Newsletter
The sheer multitude of asteroids, those known and those yet to be discovered, can be symbolically related to many of humanity’s current woes and wonders.
Surely it can be no coincidence that the first asteroid, Ceres, was discovered in 1801, just before the Industrial Revolution galvanized civilization and changed the face of our dear planet forever.
This means it broke free from the asteroid belt and crossed Mars’ orbit to arrive at its present position.

 Science Fair Projects - 3753 Cruithne
Mars has one known co-orbital asteroid ( 5261 Eureka), and Jupiter has many (about 400 objects, the Trojan asteroids); there are also other small co-orbital moons in the Saturnian system: Telesto and Calypso with Tethys, and Helene with Dione.
Three other near-Earth asteroids (NEAs), (54509) 2000 PH and 2002 AA, which exist in resonant orbits similar to Cruithne's, have been discovered.
Other examples of natural bodies known to be in horseshoe orbits at the time of writing include Janus and Epimetheus, natural satellites of Saturn.

 2000-03-22 : Asteroid 2000ew70 : Worth Hill Observatory (UK)
After four or five fields the asteroid was quite easily seen as a short streak of light in 20 sec exposures.
Each image of the asteroid is elongated as it moved during each 20 sec CCD exposure.
With a little bit of help from the Minor Planet Ephemeris Service I succeeded in tracking down the recent LINEAR discovery of 2000 EW70 which is an "earth crosser" and member of the Aten family.

 1862 Apollo - Art History Online Reference and Guide
It is also a Venus- and Mars-crosser asteroid.
It is the namesake of the Apollo asteroids, and the first one discovered, although because it was lost for a time its asteroid number (1862) is higher than that of some other Apollo asteroids such as 1566 Icarus.
It was the first asteroid recognized to cross Earth 's orbit (although the earlier-discovered 887 Alinda is now known to do so as well).

Asteroid 1998 WT24 approaches within 0.0125 AU (4.9 Earth-Moon distances) in Dec. 2001, its closest for at least several centuries.
The available optical astrometry permits reliable integration of the asteroid's rather frequently perturbed orbit during 1764-2482, but radar astrometry would allow much more extended predictions.
Currently, the asteroid closely approaches the Earth at half-century intervals.
