Question
Asteroids (10)1. (a) There are regions in the asteroid belt that contain few or no asteroids; asteroids at these distances would experience a resonance with Jupiter and would be pulled out of these zones. What are these asteroid-free zones called? (b) What is the name of the largest asteroid (it is also a dwarf planet and the first asteroid discovered)? (c) What is the name of asteroids trapped in Jupiter's orbit at Jupiter's Lagrange points? (d) What is the name of asteroids that cross the orbits of Jovian planets, or lie between these orbits? (e) What name is given to asteroids that cross the Earth's orbit (be very specific!? (6) 2. The three compositional varieties of asteroids are C-type, S-type and M-type. (a) What type asteroid is the most common in the inner asteroid belt? (b) What type is most common in the outer asteroid belt? (c) Which type of asteroid appears to be metal-rich and might be mined for these metals in the future?Explanation / Answer
(10) 1. (a) The region in the asteroid belt which contain few or no asteroids is known as Kirkwood gaps.
(b) The name of the largest asteroid which is also a dwarf planet and the first asteroid discovered is Ceres.
(c) The asteroids trapped in Jupiter's orbit at Jupiter's lagrange points are known as Trojan asteroids.
(d) The name of the asteroids that cross the orbits of Jovian planets or lie between these orbits are comets.
(e) The asteroids which cross the Earth's orbit are known as Earth crossers. They are mostly the near Earth asteroids which can be further classified into two types namely Aten asteroids and Apollo asteroids.
(6) 2. (a) S-type asteroids dominate the inner asteroid belt. They are much rarer in the outer belts.
(b) C-type asteroids are more common in the outer asteroid belt. The "C" here stands for carbon and these asteroids are almost coal-black and carbonaceous.
(c) M-type asteroids are metal rich. The "M" here stands for metallic and these asteroids might be mined for metals in the near future.
