Jupiter, despite being the biggest planet, has the shortest day. It takes Jupiter less than 10 hours to rotate around its axis once. Jupiter rotates at a speed of over 28,000 miles per hour, compared to Earth rotating at just over 1,000 miles per hour (at the equator).
No, the planet with the shortest revolution does not necessarily have the shortest rotation. Revolution refers to the time it takes for a planet to complete one orbit around the sun, while rotation refers to the time it takes for a planet to complete one full spin on its axis. These two periods can be different for each planet.
No planet orbits Earth.
Mercury
It differs from planet to planet
Rotational Period .
Its rotational period.
A day is defined as the time it take a planet to revolve once on it's axis. So it is the time it takes for a planet to "spin" once.
Its rotational period.
The period of rotation is the time required for a planet to spin around once on its axis. For Earth it is about 23 hours and 56 minutes.
A "year" is the time it takes for the earth to orbit the sun. Each planet has it's own year. A "day" is how long it takes for the planet to spin all the way around.
Jupiter in the planet with the shortest rotation time, with a day approximately 12 hours long.
Of the known planets in the solar system, Mercury, being nearest to the sun, completes its orbit in the shortest time . . . 88 earth days.
