Question

Name the comet which appears after every 76 years:
A) Hallets
B) Meteor
C) Halleys
D) Pole star

Answer 1

Hint: A comet is an icy, small solar system body that when passing close to the sun warms and begins to release gases. This process is known as outgassing. We need to examine each of the options and answer the question.

Complete step by step answer:
Comets can be classified as cosmic snowballs of frozen gases, rock and dust that orbits the sun. When frozen they are the size of a small town. When a comet’s orbit close to the sun, it is heated up and spews dust and gases into a giant glowing head larger than most planets.

Halley's Comet is designated as 1P/ Halley, which is a short period comet visible from earth every 75 -76 years. The Halley Comet, is the only known short period comic that is regularly visible to the naked eye from earth and the only naked comet that can appear twice in a human lifetime.

Therefore, the answer to the question is Option C.

Additional Information:
A meteoroid is a small rocky or metallic body in outer space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects.
A pole star or a polar star is a star, preferably bright, nearly aligned with the axis of a rotating astronomical body.

Note: The last time Halley's Comet was here was in 1986 and it is projected to return in 2061. The radius of the Halley's comet is 5.5 km.
