  1. freezing caused when they pass through the atmosphere

  2. vapourization caused when they pass through the atmosphere

  3. greater force of attraction towards sun

  4. greater force of attraction towards moon

Which of the following is NOT true for comets?

  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 Kuiper 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 comets 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 often contain significant amounts of water

A Correct answer
Explanation

In addition to celestial objects like $\textit{Comets}$, we also have  $\textit{Asteroids}$ which are small rocky bodies orbiting the sun and mostly found in the belt (region) between Mars and Jupiter. While there are also other asteroids lying beyond this region whose paths often come in close proximity with orbit of earth. \par Many a times collision between two asteroids, can result in small pieces breaking off from the bodies. These pieces are called $\textit{meteoroids}$. If a meteoroid enters the earth's atmosphere, it vaporizes and turns into a $\textit{meteor}$.

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

The tail of a comet is directed away from the sun because.

  1. The radiation emitted by the sun exerts a radial pressure on the comet throwing its tail away from the sun

  2. As the comet rotates, the lighter mass of the comet is attracted by some star situated in the direction of its tail

  3. As the comet rotates around the sun, the lighter mass of the comet is pushed away due to the centrifugal force alone

  4. The tail of the comet always exists in the same orientation

A Correct answer
Explanation

As a comet approaches the sun, solar radiation pressure and the solar wind push the ionized gases and dust particles away from the sun, creating the characteristic tail.

Plutons are the members of solar system with highly titled orbits. This statement is

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Answer is A.

The planet Pluto and objects beyond it are called Plutons and they are the new members of the solar system. The order of the Plutons is Pluto, Charon and 2003 UB.
Plutons have highly tilted orbits and take more than 200 years to revolve the sun.
Hence, the statement is true.
