Question

1. 2050
2. 2070
3. 2061
4. 2056

Answer 1

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.​
