1) Describe 3 pieces of evidence that Halley's Comet has for us to identify that it is indeed a comet

Three evidences that Halley's Comet is considered a comet:

-Orbits the sun in 76 years.

- Found in the Kuiper Belt.

- Despite being a black body, it has a lot of shine.

Explanation:

Comets are bodies from outer space that are very easy to recognize.

They are balls of dust, rock and gas that have no rings or satellites and that "roam" through space.

Despite being dark and icy bodies, they seem to have a great shine when they get close to the sun due to the gas and dust they expel.

Another of its characteristics is that they take less than 200 years to orbit the Sun. Halley does it in 76 years, which qualifies it as a comet.

Finally, comets are found in the Kuiper belt, located beyond Neptune's orbit, and Halley is the best known of the comets found in this belt.
