Answer: Option B. ->
Greater the distance, greater the time period
:
B
A planet has a definite path in which it revolves around the Sun. This path is called an orbit. The period of revolution of a planet around the Sun increases as the distance of the planet increases from the Sun. Hence, greater the distance, greater is the time period.

Answer: Option D. ->
Jupiter
:
D
Jupiter is the fastest spinning planet in our Solar System. Its period of rotation is just 10 hours. This means that Jupiter has the shortest day amongst all the planets in our Solar System.

Answer: Option D. ->
Artificial satellites revolve much farther from Earth than the Moon.
:
A, B, and C
Artificial satellites are man-made and are launched from Earth. They revolve around Earth much closer than the Moon. Artificial satellites are used for weather forecasting, transmission of radio and television signals, etc.

Answer: Option A. ->
IAU
:
A
:
A
In 2006, the International Astronomical Union (IAU) adopted a new definition of a planet such that Pluto does not fit this definition. Hence, it is no longer a planet of the solar system.
Answer: Option B. ->
decreases
:
B
The size of moon decreases progressively after the full moon day, till the point it disappears completely on the new moon day. After that, it starts to increase again.

Answer: Option A. ->
Satellite
:
A
A celestial body that revolves around a planet is known as a satellite, or more precisely called a natural satellite. A natural satellite is also simply called a moon. Most of the planets in our Solar system have moons. Earth is a planet with a natural satellite, and many artifical (man made) satellites.

Answer: Option B. ->
Asteroids
:
B
There is large space between the orbits of the planets Mars and Jupiter. A large number of small objects occupy this space revolving around the Sun. These objects are called asteroids. The collection of asteroids in that region is called the asteroid belt.

Answer: Option B. ->
Neptune
:
B
:
B
The area enclosed by an orbit depends on the distance of the planet from the sun. Larger the distance, larger the area enclosed. Among the given planets, Neptune is the farthest planet so will have the maximum area enclosed in its orbit.
Answer: Option A. ->
False
:
A
:
A
Constellations are a group of stars that form recognizable shapes in the sky. Our solar system consists of only one star, i.e., Sun. Thus, constellations are not a part of our solar system.
