(a) We always see only one side of the moon because of the way the moon rotates on its own axis and around the Earth. The moon takes approximately 27 days and 8 hours to rotate on its own axis and takes the same time to revolve around the Earth.
(b) Each planet has its own independent orbit and they do not cross the orbit of any other planet. Due to this reason planets do not collide into one another.
(c) Saturn has rings around it that cannot be seen by naked eye. Also, the density of Saturn is less than that of water. So, it can float in a big sea. These are the unique characteristics of Saturn.
(d) We see the planets and stars moving from the east to the west because the Earth rotates from the west to the east about itself.
(e) Artificial satellites are useful to broadcast many type of programs such as an India-England cricket match which is played at Lords. We can watch this live cricket match at home in Delhi.
