Which of the following planets orbits the fastest around the sun?
Group of answer choices
The one which is coldest
The one which is biggest
The one which is closest to the sun
The one which is farthest from the sun
The one which is closest to the sun.
The planet that orbits the fastest around the Sun is the one which is closest to the Sun.
To find out which planet orbits the fastest around the sun among the given choices, we need to understand the concept of orbital speed. The orbital speed of a planet is determined by its distance from the sun and its mass.
Out of the given choices, the correct answer is "The one which is closest to the sun." This is because a planet's distance from the sun affects its orbital speed. According to Kepler's third law of planetary motion, the closer a planet is to the sun, the faster it orbits. The inverse square relationship between distance and gravitational force means that planets closer to the sun experience a stronger gravitational pull, which leads to higher orbital speeds.
Therefore, the planet that is closest to the sun in this group will have the highest orbital speed.
