VIRTUAL TRIP TO ASTEROID

Asteroids are minor planets (small Solar System bodies and dwarf planets) that are not comets.

They have also been called planetoids.

There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun'ssolar nebula that never grew large enough to become planets.

REFLECTION:THEREFOR, THERE HAVE LOTS OF ASTEROIDS IN OUR SOLAR SYSTEM. THEY ARE MOVING IN THE ORBITS OF PARTICULAR PLANETS SUCH AS MARS AND JUPITER.

In astronomy, a Trojan is a minor planet or natural satellite (moon) that shares an orbit with a planet or larger moon

The term "trojan" originally referred to the "trojan asteroids" that orbit close to the Lagrangian points of Jupiter.

These have long been named after characters from the Trojan War of Greek mythology.

The Hilda or Hildian asteroids are a dynamical group of asteroids in a 3:2 orbital resonance with Jupiter.

Hilda’s move in their elliptical orbits so that their aphelia put them opposite Jupiter, or 60 degrees ahead of or behind Jupiter at the L4and L5 Lagrangian points.

Over three successive orbits each Hilda asteroid passes through all of these three points in sequence.

They do not form a true asteroid family, in the sense that they do not descend from a common parent object.

The namesake is 153 Hilda, discovered by Johann Palisa in 1875.

There are more than 1,100 known Hilda asteroids including unnumbered objects.[1][3]

The orbit of Jupiter, like that of all the planets, is elliptical instead of circular.  Back

The orbit of Mars is the second most eccentric in the Solar System.

The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter.

white color It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
