Asteroids
In yesterday's newspaper , there was a news about Asteroids causing harm in Ukraine. Asteroids are small solar system bodies which are not comets.
The term asteroids historically referred to the objects inside the orbit of planet Jupiter. They are also called planetoids if they are larger in size. These are the astronomical objects that are orbiting the Sun , but they are not planet or comets .
They are usually rocky or metallic. There are millions of asteroids ! They never grew large enough to be a planet . The first asteroid to be discovered is Ceres , was found in 1801. The term asteroid refers to star like or star shaped.
The main difference between a comet and asteroids is that a comet shows a tail due to sublimation of ices by solar radiation . Comets typically have a more eccentric orbits than asteroids . Asteroids contain traces of amino acids and other organic compounds and their impact on the earth may have resulted in initiating life or destruction of life too.
Usually , they are not visible to naked eye.
