Consider the following:
1. Asteroid Belt
2. Kuiper Belt
3. Oort Cloud
Which among the following is the correct sequence of their increasing distance from Sun?

Answer: [A] 1, 2, 3

The Kuiper Belt is a doughnut-shaped ring, extending just beyond the orbit of Neptune from about 30 to 55 AU. The Oort Cloud is a spherical shell, occupying space at a distance between five thousand and 100 thousand AU. Thus, both of them are beyond the orbit of Neptune. The first mission to the Kuiper Belt is New Horizons of NASA. We note here that New Horizons is expected to reach Pluto in July 2015 before possibly heading farther into the Kuiper Belt.
