Question

Q7-Write three condition for a body to be called a planet.
​

Answer 1

Explanation:

It must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to have enough gravity to force it into a spherical shape. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.

Answer 2

Three condition for a body to be called a planet:

1. Huge Mass:

• The mass of a body defines it's enormous capacity or amount filled in it.

2. Availability:

• Things available on that huge mass, such as if there is nothing important then it will be useless, though it will be a planet but it will be useless.

3. Uniqueness:

• It may be unique from the rest planets, or there may be only one body of that much mass to be called as a planet.
