Answer» Correct Answer - Option 3 : 2061
The correct answer is 2061. - Comets are considered to come from a vast reservoir, the Oort cloud, orbiting the Sun at distances of 20,000–50,000 AU or more and containing trillions of icy objects which have the potential to become active comets.
- Halley’s Comet is the best known of these periodic comets; its next return into the inner solar system is predicted for 2061.
- Many short-period comets are thought to come from the Kuiper belt, a region lying mainly between 30 AU and 50 AU from the Sun.
- Smaller than the observed asteroids and comets are the meteoroids, lumps of stony or metallic material believed to be mostly fragments of asteroids.
- Pluto, Eris, and Ceres, the latter being the largest member of the asteroid belt.
- Two other Kuiper belt objects, Makemake and Haumea, were also designated as dwarf planets.
