How long is a year on each planet?
A year is the time it takes the earth to make one revolution – a little over 365 days….The Days (And Years) Of Our Lives.
| Planet | Rotation Period | Revolution Period |
|---|---|---|
| Venus | 243 days | 224.7 days |
| Earth | 0.99 days | 365.26 days |
| Mars | 1.03 days | 1.88 years |
| Jupiter | 0.41 days | 11.86 years |
Which planet is longer than its year?
Venus The study found that a single Venusian rotation takes 243.0226 Earth days. That means a day lasts longer than a year on Venus, which makes a complete orbit around the sun in 225 Earth days.
Does Mars have the longest year?
Mars' orbit Mars lies farther from the sun than Earth does, so the Red Planet has a longer year — 687 days compared to 365 for our home world. The two planets have similar day lengths, however; it takes about 24 hours and 40 minutes for Mars to complete one rotation around its axis, versus 24 hours for Earth.
What planet has the shortest year?
Mercury Fastest Planet The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.

Do u age slower in space?
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
How old would I be on Mars if I was 12?
A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.
Which planet has the shortest year?
Mercury Fastest Planet The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.
How long is Venus year?
225 daysVenus / Orbital period Venus rotates very slowly on its axis – one day on Venus lasts 243 Earth days. The planet orbits the Sun faster than Earth, however, so one year on Venus takes only about 225 Earth days, making a Venusian day longer than its year!
How long is Martian year?
687 daysMars / Orbital period The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
Which planet has the longest month?
How long is a day on each planet?
| Planet | Length of Day | |
|---|---|---|
| Uranus | 0.7 | 17.2 |
| Neptune | 0.7 | 16.1 |
| Saturn | 0.45 | 10.7 |
| Jupiter | 0.41 | 9.9 |
What is Mercury’s period?
The planet's rotation period of 58.6 Earth days with respect to the stars—i.e., the length of its sidereal day—causes the Sun to drift slowly westward in Mercury's sky.
Does Earth have 3 moons?
The simple answer is that Earth has only one moon, which we call “the moon”. It is the largest and brightest object in the night sky, and the only solar system body besides Earth that humans have visited in our space exploration efforts. The more complex answer is that the number of moons has varied over time.
Can a moon have a moon?
Yes, it is possible for a moon to itself have moons and/or rings, and there are a few places where scientists have suggested that this is (or was) the case. However, moons tend to rotate slowly, and this makes it difficult for a moon's moon to find a stable orbit.
Do astronauts get paid for life?
So, while they may not be paid for life, astronauts do receive many benefits that help offset the risks of their profession. However, astronauts may enjoy many potential financial rewards once they retire.
How is 1 hour in space equal to 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
Do you age differently in space?
In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.
Is Earth older than Mars?
“Mars is believed to be geologically older than Earth, yet (both) formed out of the same material very close to each other,” Matthew Clement, the paper's lead author and a graduate researcher in planetary science at the University of Oklahoma, told me.
What planet has no seasons?
Mercury Mercury is also the only planet in our solar system without any tilt, so technically lacks seasons. But what it does have is a highly elliptical orbit, creating a version of summer and winter.
How long is Mars year?
687 daysMars / Orbital period The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year. That longer year means longer seasons too.
What is Earth’s twin planet?
Venus Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
Do you age in space?
In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.
Is Earth or Mars older?

What planet has shortest year?
Mercury Fastest Planet The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.
What planet has the shortest and longest year?
Which planet has the longest day and the shortest year? The answer to both questions is Mercury.
Which planet has shortest year?
Mercury Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.
Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.
Does Earth have 2 moons?
MoonEarth / Moon The simple answer is that Earth has only one moon, which we call “the moon”. It is the largest and brightest object in the night sky, and the only solar system body besides Earth that humans have visited in our space exploration efforts.
What planet has 47 moons?
The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to enormous Titan, which is larger than the planet Mercury.
