There are various types of man-made satellites revolving
in their respective orbits in outer space. Satellites are invented
for communication purposes, weather forecasts and Earth
observations. Why are these satellites able to revolve in their
respective orbits?
Several hundred years ago, Isaac Newton, a scientist,
conceptualised a universal law connecting all heavenly bodies
and also man-made satellites. Curiosity about the universe has
encouraged scientists to launch spaceships and satellites which
can overcome the Earth’s gravity. At present, there are spaceships
which are moving far away from Earth. Such spaceships enable
photographs of planets to be taken to benefi t scientifi c inventions
and technology.
