The correct answer to this question is option C
The farthest planet from the sun is Neptune. It orbits around the sun in an elliptical orbit. It is about 4.45 billion km away from the sun and orbits out at about 4.55 billion km away.
It takes Neptune 165 years to complete one orbit around the sun.
Option B is incorrect because Earth is the third closest planet to the sun.
Option C is also incorrect because the Uranus is also far from the sun but not as far as Neptune. It is the 7th planet away from the sun.
Option D is incorrect as Pluto is no longer the farthest planet from the sun because it is no longer regarded as a planet. Pluto is said to be about 4.44 billion km away from the sun.
The correct answer to this question is B, Neptune. There are eight planets, and Neptune is the furthest away. It is a gas giant. Experts believe that before it's current position, Neptune was originally closer to the Sun. 165 Earth years equate to one Earth Year.
The name Neptune comes from the Roman god of the sea. The first observation of Neptune came in 1846, which is when the name came about. This planet has 14 moons and six rings that are faint. The atmosphere of Neptune is thick. It is made of 25% helium, 1% methane, and 74% hydrogen.
