  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Despite its name, shooting stars are not actually stars. Shooting star is either a piece of a small rock or dust from space that heats up when is enters the Earth's atmosphere. Shooting stars are basically meteors.

  2. Constellations

  3. Meteors

  4. Both A and C

Show answer
Correct Option: D
Explanation:

Which of the following is NOT true for comets ?

evs - i our earth and our solar system asteroids, comets, and meteors and meteorites other objects in solar system asteroids, comets and meteors

  1. Some comets are believed to have originated in a region near the edge of the orbit of the outer planets in our solar system called the "scattered disk" that overlaps a region called the Kulper belt.

  2. Some comets are believed to have originated in the outer-most region associated with our solar system, called the Oort cloud.

  3. The tail of a comet gives the comet its propulsion, like rocket fuel out the back end of a rocket.

  4. The tails of a comet generally point away from the Sun and are made of two major parts - a dusty part (that curves a bit) and an ionic part.

  5. Comets of ten contain significant amount of water.

Show answer
Correct Option: C
Explanation:

In the outer Solar System, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas thus released form a huge, extremely tenuous atmosphere around the comet called coma, and sun's radiation pressure and solar wind cause the tail to point away from the Sun.

All the facts stated in the options are correct except for option C.
Correct answer is option C.

Why tail of comets is formed ,when it comes closer to sun ?

evs our solar system asteroids, comets, and meteors and meteorites other objects in solar system asteroids, comets and meteors

  1. Ice presents in the comets gets vapourised

  2. When is comes closer to sun ,vapour converts in to ice

  3. Dust particle in the comets gets heated

  4. Water present in comets gets cooled

Show answer
Correct Option: A
Explanation:

The tail of comets so formed, When comets come closer to the sun, because the sun's heat vaporizes some of the comets' material, releasing dust particles that were trapped in the ice.

The correct option is A.

Which is the first and biggest asteroid discovered? 

evs our solar system asteroids, comets, and meteors and meteorites other objects in solar system asteroids, comets and meteors

  1. Vesta

  2. Titan

  3. Ceres

  4. Charon

Show answer
Correct Option: C
Explanation:

The first and largest, Ceres, was discovered Jan. 1, 1801, by the Italian astronomer Father Piazzi (1746–1826).

The tail of a comet always points__________ .

evs - i our earth and our solar system asteroids, comets, and meteors and meteorites other objects in solar system asteroids, comets and meteors

  1. towards the sun

  2. away from the sun

  3. towards north-east

  4. towards south-west

Show answer
Correct Option: B
Explanation:

The streams of dust and gas thus released from a huge extremely tenous atmosphere around the comet called coma and force exerted on coma by the sun's radiation pressure and solar wind cause an anormous tail form which points away from the sun
