Q.how many times, since the big bang, has the moon orbited the earth?
A.Since the Big Bang, and Earth's creation 4.57 billion years ago, the moon has completed about 64 billion orbits. It moves 4cm away from us every year.
A.The Earth spins at 1,000 mph at the equator & travels through space at 67,000 mph. The Earth moves around the sun via a gravitational centripetal force.
Q.How was the Earth formed?
A.Earth originated from a swirling mass of molten rock orbiting the sun, which coalesced under gravity. Atoms are formed by nuclear fusion in stars.
Q.wat causes all the planets not to bang together?
A.The planets are held in their orbits by the gravitational forces of the Sun and the other surrounding planets, which stops them colliding.
Q.Have the tides got something to do with the moon?
A.Tides are caused by the gravitational pull of the moon on the seas & oceans. As the moon orbits Earth, the direction in which it pulls the water changes.
Q.How many times does the moon orbit the earth in one day?
A.The Moon orbits the Earth once every 27.3217 days, or 13.359 times in a year. The Moon always keeps the same face towards Earth.
