Question

Write short note on any one: (02) a)Solar System b)Equinox​

Answer 1

Answer:

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies.

Answer 2

Explanation:

The Solar System is about 4.6 billion years old.[1] It formed by gravity in a large molecular cloud. Most of this matter gathered in the center, and the rest flattened into an orbiting disk that became the Solar System. It is thought that almost all stars form by this process.

The Sun is a star. It contains 99.9% of the Solar System's mass.[2] This means that it has strong gravity. The other objects are pulled into orbit around the Sun. The Sun is mostly made out of hydrogen, and some helium and higher elements.
