ATEN ASTEROID
Atens are asteroids that are always closer to the Sun than the Earth is; they have a period shorter than 1 year (the semi-major axis is smaller than Earth's). They were named for asteroid Aten, #2062. Ra-Shalom is an Aten asteroid.

For example, the perihelion of the Aten asteroid Icarus (Figure 14.4) is within 0.2 A.U. of the Sun. On its way past Earth in 1968 it missed our planet by "only" 6 million km"a very close call by cosmic standards.

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.

Near-Earth Asteroid: Apollo, Amor, and Aten asteroids.
Neutrino: An elementary particle that is almost massless and very rarely interacts with other forms of matter.

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.

This Aten asteroid, which has a diameter of about 300 metres, is predicted to pass within 32,000 km of Earth—i.e.

Most are in the Asteroid Belt, which lies between Mars and Jupiter. Many more share the orbit of Jupiter; they are known as the Trojan Asteroids. Some are closer to the Sun than the Earth's orbit; these are known as the Aten Asteroids.
