Answer 1

Everything in nature tries to be at its minimum potential energy. Planetary objects stay in their places due to their gravitational potential energy, they tend to stay at a distance where its minimum

The relative positions of the stars in the night sky

are absolutely fixed and therefore we can name constellations with certainty.

change appreciably over about four thousand years, which is why the ancient. Egyptians named different constellations than those of today

are changing, but very slowly such that appreciable change cannot be observed even over several centuries or even several thousand years.

appear to change because the sun moves among them over the course of a year.

The planets keep changing their position with respect to:

A star is seen to be rising on the eastern horizon at $23 : 00$ hrs. At what time the star will rise 2 days later

The movement of Moon around Earth is called

Do all the stars in the sky move? Explain.

Paheli saw the moon through a glass window at 8:00 p.m. She marked the position of the moon on the glass pane. She got up at 4 a.m. in the morning. Will the moon be visible at the same position? (yes/no)
