Question

A star like body with long tail is called:
A. Comet
B. Meteor
C. Meteorite
D. Pluton

Answer 1

Hint: A star-like body with a long tail, is actually a heavenly body which can be seen from the earth’s surface. It is actually a meteorite moving with high speed and the sunlight pushes away some gases from the head of the meteorite due to which it appears to develop a tail.

Complete step by step answer:
COMETS
A comet is a heavenly body with a long glowing tail of light behind it. It is also called 'tailed star'.Comets also are members of the sun's family like other heavenly bodies. A comet has three parts- nucleus, coma, and tail. The nucleus is the brightest part of the comet. Composed of ice, dust, and gas, the dirty snowball called the nucleus shines through the center of its head. The part surrounding the nucleus is called a coma. It is made up of gases and dust and may have a diameter of more than 2 million km. The tail is an important part of a comet. The tail is of two varieties- dust tail and plasma tail. A comet generally tends to develop a tail whenever it comes close to the sun. The sunlight pushes away some amount of gas from its head. It is this gas which starts showing and looks like a tail. As the comet goes nearer to the Sun, it approaches with great speed along with its bright shining tail.

Therefore the correct option is option A, Comet.

Note: Heavenly bodies that revolve around the sun and appear as bright as a glowing ball with a long tail is called a comet. It may have a diameter of 100 to 10,000 meters. The length of a dust tail may vary from 1 to 10 million km, while that of a plasma tail, composed of extremely hot ionized gases, up to 100 million km.
