Answer:
According to the nebular hypothesis, our solar system is formed from a huge rotating cloud made mostly of helium and hydrogen.
Explanation:
The nebular hypothesis was proposed by I. Kant. It explains the formation and evolution of the Solar System. It is considered and accepted widely. The theory states that the Solar System was formed from a nebulous material. And as per nebular hypothesis, stars create the huge, dense clouds of molecular hydrogen. This hypothesis tries its best to describe the formation of the solar system from a nebula cloud that was made of a collection of dust and gas. It is also believed that the sun, planets, moons and asteroids were also born around the same time that is, around 4.5 billion years ago from a nebula.

Answer:
<u>Time is measured in Lunar month </u>
Explanation:
- The lunar month is the time the moon takes to pass through each phase i.e new moon to half and then to the full moon etc. Taking about 29 days, 12 hours, 44 minutes and 3 seconds to complete this rotation on its axis.
- Thus the moon only takes 27.3 days to complete this action. Thus as the moon goes back in its orbit it takes 2.2 days to catch up. Moon also has the same elliptical longitude as that of the sun as seen from the earth's surface.
- The motion of the moon is in an eastward direction along with the motion of stars, thus it shows the same face to earth every day. This is evident as it moves just 13 degrees in 24 hours.
