181.	The celestial body revolving around the Sun between the planets Mars and Jupiter is called?
	A. comet
	B. Meteorite
	C. Meteor
	D. Asteroid Option “D” is correct. Asteroids are small rocky bodies that orbit the Sun, mainly between Mars and Jupiter, in a strip known as the asteroid belt.

182.	The planets between which asteroids are found are –
	A. Mars and Venus
	B. Jupiter and Saturn
	C. Mars and jupiter
	D. Saturn and Uranus Option “C” is correct. Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt.

183.	The first discovered asteroid is –

	B. Palas
	C. Juno
	D. Vesta Option “A” is correct. In 1801, while making a star map, Giuseppe Piazzi accidentally discovered a small object 1000 kilometers (600 miles) in diameter between the orbits of Mars and Jupiter. Piazzi named the object Ceres. It was the first asteroid to be discovered.

184.	The tail of a comet is directed away from the Sun because –
	A. As the comet revolves around the Sun, its light mass gets scattered away due to centrifugal force alone.
	B. As the comet rotates, its light mass is attracted by a star located in the direction of its tail.
	C. The radiation emitted by the Sun exerts pressure on the comet due to which its tail is deflected away from the Sun.
	D. Comet tails always remain in the same orientation Option “C” is correct.

185.	Consider the following statements about asteroids – I. Asteroids are rocky debris of various sizes orbiting the Sun. II Most of the asteroids are small but some have a diameter of 1000 km. is as large as III. The orbit of the asteroids lies between the orbits of Jupiter and Saturn.
	A. I, II and III are correct.
	B. II and III are correct.
	C. I and II are correct.
	D. I and III are correct. Option “C” is correct.

186.	During solar eclipse-
	A. The Earth comes between the Sun and the Moon.
	B. The Moon comes between the Sun and the Earth.
	C. The Moon comes exactly half the distance between the Earth and the Sun.
	D. The Sun comes between the Earth and the Moon. Option “B” is correct. A solar eclipse occurs when the Moon passes between Earth and the Sun, fully or partially obscuring the Sun’s disk. A lunar eclipse occurs when the Moon passes through Earth’s shadow, fully or partially darkening the lunar disk.

187.	Which part of the Sun is visible during a total solar eclipse?
	A. The Corona
	B. Circle of light
	C. Varna Mandal
	D. None of these Option “A” is correct. Few minutes of the total solar eclipse are the only times we on Earth can see the corona, the Sun’s upper atmosphere, which streams out into space above the sun’s surface. Normally, the corona’s delicate light is outshone by the bright photosphere.

188.	In which of the following situations does a solar eclipse occur?
	A. When the Moon comes between the Earth and the Sun.
	B. When the Earth comes between the Sun and the Moon.
	C. When the Sun, Moon and Earth are situated at right angles.
	D. There is no fixed time for this. Option “A” is correct.

189.	The condition of solar eclipse is found – I. When the Earth comes between the Moon and the Sun. II. When the Moon comes between the Sun and the Earth. III. When it is the day of Amavasya. IV. When there is a full moon day.
	A. II and IV are correct.
	B. I and III are correct
	C. II and III are correct.
	D. I and IV are correct. Option “C” is correct.

190.	What is the maximum number of eclipses that can occur in a calendar year?
	A. 5
	B. 7
	C. 9
	D. 11 Option “B” is correct. Most years have four eclipses: the minimum number of eclipses in a year; 2 of these four eclipses are always solar eclipses. While rare, the maximum number of eclipses that can take place in a calendar year is seven. There are two or three eclipses during every eclipse season.
