Dear Student

Q : 01
Ursa Major: It can be seen during summer time in the early part of the night. It is also know as saptnrish
Great Bear' or 'Big Dipper'. The name 'Big Dipper' has been derived from the word 'Dipper'. Dipper was used in olden days for drinking water
Ursa Major consists of a groups of seven stars. Three stars appear to form the handle of the dipper and four stars form its bowl. It appears to move from east to west in the sky.

Q : 02
The basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. Just as the Moon orbits the Earth because of the pull of Earth's gravity, the Earth orbits the Sun because of the pull of the Sun's gravity.
​​​​​​
​The planets orbit the Sun because they’re left over from the formation of the Solar System. Their current motion depends on the gravitational attraction of the Sun at the center of the Solar System. In fact, they’re in perfect balance

There are two opposing forces acting on the planets: gravity pulling them inward, and the inertia of their orbit driving them outwards. If gravity was dominant, the planets would spiral inward. If their inertia was dominant, the planets would spiral outward into deep space.

The planets are trying to fly out into deep space, but the gravity of the Sun is pulling them into a curved orbit.
