Mercury takes the least days to orbit around the sun because it is very near to it the correct answer is 88

Mercury's Orbit around the Sun

Introduction:
Mercury is the closest planet to the Sun in our solar system. It orbits around the Sun just like all the other planets. The time it takes for a planet to complete one orbit around the Sun is known as its orbital period.

Explanation:
Mercury takes approximately 88 days to complete one orbit around the Sun. This means that it completes 1 year on Mercury in about 88 Earth days. Let's explore some key points about Mercury's orbit:

1. Shortest Orbital Period:
Mercury has the shortest orbital period among all the planets in our solar system. It is much closer to the Sun compared to other planets, which results in its faster orbit.

2. Distance from the Sun:
Mercury's close proximity to the Sun influences its orbit. The average distance between Mercury and the Sun is about 57.9 million kilometers (36 million miles). This distance is much smaller compared to other planets like Earth, which is about 149.6 million kilometers (93 million miles) away from the Sun.

3. Elliptical Orbit:
Mercury's orbit is slightly elliptical, meaning it is not a perfect circle but rather an elongated shape. This elliptical orbit causes variations in the distance between Mercury and the Sun during different parts of its orbit. However, the difference in distance is relatively small compared to other planets.

4. Orbital Speed:
Due to its close proximity to the Sun, Mercury travels at a high speed in its orbit. Its average orbital speed is about 47.87 kilometers per second (29.81 miles per second). This high speed helps Mercury complete its orbit in a shorter time compared to planets farther away from the Sun.

Conclusion:
In summary, Mercury takes approximately 88 Earth days to complete one orbit around the Sun. Its close proximity to the Sun, elliptical orbit, and high orbital speed contribute to its relatively short orbital period. Understanding the orbital periods of planets helps us study and explore the dynamics of our solar system.
