Answer 1

Correct Answer - Option 3 : 2062

Concept:

Comets

• Comets move around the Sun in regular orbits.
• Comets are made up of frozen gases that hold together rocky and metallic materials.
• Comet is visible only when it travels close to the Sun.

Halley Comet

• Halley was last seen in Earth's skies in 1986 and was met in space by an international fleet of spacecraft.
• It will return in 2061 on its regular 76-year journey around the Sun.
• The radius of Halley's Comet is 5.5 km.
• Halley's comet was discovered in 1758.
• Comet Halley moves backwards (opposite to Earth's motion) around the Sun in a plane tilted 18 degrees to that of the Earth's orbit.

Explanation:

So, Halley Comet is seen after 76 yeas from 1986.

1986 + 76 = 2062

So, it will be seen in 2062.
