So, Venus has the longest day of any planet in our solar system.
It completes one rotation every 243 Earth days.
Its day lasts longer than its orbit.
It orbits the Sun every 224.65 Earth days, so a day is nearly 20 Earth days longer than its year.
Which 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. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.
Which planet has days longer than 24 hours?
On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours.
Is a day longer than a year on Mercury?
A planet’s day is the time it takes the planet to rotate or spin once on its axis. Mercury rotates very slowly compared to Earth so a day on Mercury is much longer than a day on Earth. A day on Mercury is 58.646 Earth days or 1407.5 hours long while a day on Earth is 23.934 hours long.
How long does it take to travel to each planet?
Earth takes 365 days to travel one complete orbit, while Mercury takes 88 days and Venus takes 224 days, so the time between alignments will require each planet to make a whole number of orbits around the sun and return to the pattern you see in the figure above.

How long is Mars Day?

Why is a day on Jupiter so short?
This means that Jupiter has the shortest day of all the planets in the Solar System. Since Jupiter is a gas planet, it does not rotate as a solid sphere. Jupiter’s equator rotates a bit faster than its polar regions at a speed of 28,273 miles/hour (about 43,000 kilometers/hour).
What is the best planet?
Planets in Our Solar System
- Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon.
- Venus. Venus spins slowly in the opposite direction from most planets.
How long is a day on Pluto?
Pluto rotates much more slowly than Earth so a day on Pluto is much longer than a day on Earth. A day on Pluto is 6.4 Earth days or 153.3 hours long.
What would a day on Mercury be like?
The planet closest to the sun has no atmosphere, oceans or visible signs of life. While mostly very hot on its day side, the poles are cold enough to support megatons of water ice. Full Story: What Would It Be Like to Live on Mercury? To an astronaut standing on its surface, Mercury would appear similar to the moon.
Is Mercury the hottest planet being closest to the sun Why?
Because it is so close to the sun, it can be very hot. On its sunny side, Mercury can reach a scorching 800 degrees Fahrenheit! (But Mercury is not the hottest planet in the solar system. The hottest planet is Venus.)
Why is Mercury so cold at night?
Despite its proximity to our star, Mercury is not the hottest planet in the solar system. With no atmosphere to trap heat, surface temperatures on Mercury can swing from 800 degrees Fahrenheit during the day to -290 degrees Fahrenheit at night.
Does time go slower in space?
As you move faster in space, time goes slower. As seen in the movie, “Interstellar,” Earth’s surface has a higher gravity than the Martian surface, so on Mars you will experience your seconds slightly faster than people on Earth.
Are we all moving at the speed of light?
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
Why is the day 24 hours?
Our 24-hour day comes from the ancient Egyptians who divided day-time into 10 hours they measured with devices such as shadow clocks, and added a twilight hour at the beginning and another one at the end of the day-time, says Lomb. “Night-time was divided in 12 hours, based on the observations of stars.
Which planet has the longest seasons?
Each planet in the solar system has seasons. Earth has four seasons. Most planets do, too. They are called winter, spring, summer and fall.
|PLANET||LENGTH OF SEASON|
|Saturn||About 7 years|
|Uranus||About 20 years|
|Neptune||More than 40 years|

Could you fly a drone on Mars?
NASA to decide soon whether flying drone will launch with Mars 2020 rover. An internal battery is capable of powering the drone for flights lasting between 90 seconds and 2 minutes — enough time to travel up to 1,000 feet, or 300 meters — and solar panels can recharge the battery for subsequent flights, Watzin said.
Is there sunlight on Mars?
Mars’ greater distance from the Sun means that the maximum intensity (brightness) of sunlight on Mars is much less (about 44%) than that on Earth.
Does time go faster on Mars?
Because its orbital eccentricity is greater than that of Earth, the length of day varies from the average by a greater amount than that of Earth, and hence its equation of time shows greater variation than that of Earth: on Mars, the Sun can run 50 minutes slower or 40 minutes faster than a Martian clock (on Earth, the
Does Jupiter have an atmosphere?
The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water.
How long does a day last on Jupiter?

Is Jupiter bigger than Earth?
Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.
Is Saturn a livable planet?
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. It has only one-eighth the average density of Earth, but with its larger volume Saturn is over 95 times more massive.
What is the most habitable planet besides Earth in our solar system?
Despite this, some scientists estimate that there are as many habitable exomoons as habitable exoplanets. Given the general planet-to-satellite(s) mass ratio of 10,000, large Saturn or Jupiter sized gas planets in the habitable zone are thought to be the best candidates to harbour Earth-like moons.
Does Pluto have an atmosphere?
The atmosphere of Pluto is the tenuous layer of gases surrounding Pluto. It consists mainly of nitrogen (N2), with minor amounts of methane (CH4) and carbon monoxide (CO), all of which are vaporized from their ices on Pluto’s surface.
