Mercury; a year on Mercury takes only 88 Earth days.
What planet has the shortest year?
Mercury is an extreme planet in several respects. Because of its nearness to the Sun—its average orbital distance is 58 million km (36 million miles)—it has the shortest year (a revolution period of 88 days) and receives the most intense solar radiation of all the planets.
What inner planet has the shortest day?
The planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec.
Do inner planets have longer years?
Because they are quite close to the Sun, the Inner Planets complete an orbit quickly. … The Outer Planets orbit the Sun from millions of miles and have a much greater distance to cover to complete an orbit, so take much longer to do so. Jupiter takes almost 12 years to complete an orbit and Neptune takes over 164 years.
Which planets have the longest and shortest years?
Which planet has the longest day and the shortest year? The answer to both questions is Mercury. It orbits the Sun every 88 days, and a Solar Day on Mercury lasts for two orbits which is 176 days.

What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
How long is 1 hour in space?
1 hour in space is 7 years on earth.
Why is Venus the hottest planet?
Similar in structure and size to Earth, Venus spins slowly in the opposite direction from most planets. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.
What planet has the longest days?
Venus has the longest rotation period (day) of all the major planets in the Solar System.
