Apollo Asteroid
The Apollo asteroids are a class of with -crossing orbits. The first Apollo asteroid was discovered in 1918 by Max Wolf observing from Heidelberg, Germany.

Apollo Asteroid
One of a small group of asteroids whose orbits intersect that of Earth. They are named for the prototype, Apollo (P = 622d, a = 1.486 AU, e = 0.57, i = 6°.4).

Apollo asteroids (NASA Thesaurus) Earth grazing asteroids in orbits between Mars and Jupiter, and crossing the Earth's orbit. This group contains 19 known asteroids.

APOLLO OBJECT or APOLLO ASTEROID
Apollo asteroids have an orbit that crosses the orbit of the Earth and have a period longer than 1 year. They have a semimajor axes greater than 1 astronomical unit (au), and perihelion distances less than 1.017 au.

In 1968 the Apollo asteroid (1566) Icarus became the first NEA to be observed with radar. Some four decades later about 200 NEAs had been so observed.

The first of these to be discovered were the Apollo asteroids, 1862 Apollo being detected by the German astronomer Karl Wilhelm Reinmuth in 1932 but lost shortly thereafter and not rediscovered until 1978.

By the late 1980s, about 75 asteroids, the Amor asteroids, were known to intersect the orbit of Mars, about 50 Apollo asteroids to intersect the orbit of the earth, and less than 10 Aten asteroids to have orbits smaller than the earth's orbit.

An Apollo asteroid (a type of near-Earth asteroid) that passed the Earth at the relatively close distance of 432,000 km (269,000 miles) - 1.1 times the Earth-Moon distance - on Jul. 3, 2006 (closest approach at 04:25 UT).

One kind of asteroid, called Apollo asteroids, cross the orbit of the earth as they move around the sun. Scientists think that an Apollo asteroid struck the Earth about 90 million years ago in the time of the dinosaurs.

These are called Apollo asteroids. It is possible that collisions between such asteroids and the Earth could occur but they are only likely on a time scale of tens of thousands of years.

Of those there are 330 Aten asteroids, 1,613 Amor asteroids, and 2,181 Apollo asteroids. There are 792 NEO's which are classified as potentially hazardous asteroids.

Some of them may burn out, leaving inert residues of stony material-possibly cataloged in some cases as Apollo asteroids of spectral class C, P or D.

The Geminids are a bit different. The appear to be travelling in the same orbit as Apollo asteroid 3200 Phaethon. Is this an asteroid that perhaps was once surrounded by and icy snowball of cometary matter?
