My Age on Jupiter Calculator

Note: When you run this calculator the birth date you enter is saved in a temporary (session) cookie so you do not have re-enter if running the calculator multiple times while visiting our site. The cookie is automatically deleted when your browser closes.

Entry Fields

In the Date of Birth fields, enter your birth date, or of the person for whom you are calculating.

If you prefer to enter Years Old instead of Date of Birth, use this field. If both are provided, Years Old takes priority, and birth date is not used. At this time, Years Old should be a whole number (e.g. 30 Years old, not 30.2 or 30.5).

In the Person's Name , enter the name of person whose Jovian age you are calculating. If calculating how old you would be on Jupiter, you can leave this field empty.

About Age on Jupiter Calculator

This calculator translates anyone's current Earth age to their age on the planet Jupiter. In addition, if birth date is provided, a birthday chart compares milestone ages (e.g. 1, 10, 16, 21, 30, 60) on Earth and Jupiter.

Below you'll find some really interesting info about Jupiter, including if one ages faster or slower on Jupiter, and how long a day lasts, as compared to here on Earth.

What is Jupiter's Position From Sun?

Jupiter is the fifth planet from the Sun. Jupiter is also the largest planet in our Solar System.

Jupiter's distance from the sun is an average distance of 484 million miles (778 million kilometers), which is 5.2 astronomical units (AU) away from the Sun.

Jupiter has two neighboring planets: Mars, fourth planet from the Sun, and Saturn, the sixth planet from the Sun.

The average distance from Jupiter to Mars is 342 million miles (half a billion kilometers).

The average distance from Jupiter to Saturn is 403 million miles (649 million kilometers). That's almost the same distance as Jupiter is from Earth.

Note that planet distance's from the Sun and one another vary based on where each planet is in its orbit around the Sun.

What is Temperature on Jupiter?

Temperatures in Jupiter's clouds are approximately -234 Fahrenheit (-145 Celsius); Near Jupiter's surface* the temperature is about -166 Fahrenheit (-110 Celsius).

Jupiter's being cold makes sense given its distance away from the Sun. However, it is believed that its core is 43,000 Fahrenheit (24,000 Celsius) - hotter than the Sun!

* Jupiter is known as one of the Gas Giants, since it is comprised mainly of gases and liquids, so it doesn't actually have a surface.

What is Jupiter's Circumference and Diameter?

Jupiter is the largest planet, with a diameter of 86,881 miles (139,821 kilometers), The diameter of a planet is the distance from one side across to the other, measured from the planet's center.

Jupiter's circumference is 272,946 miles (439,264 kilometers). A planet's circumference is the distance all the way around its equator.

Jupiter is almost 11 times larger than our earth.

When was Jupiter discovered?

Jupiter is one of 5 planets that can be viewed from Earth without the aid of a telescope or binoculars, and was observed in ancient times.

Based on its large size, the Romans named it Jupiter, after the King of the Roman gods, also referred to as Jove, and hence the term Jovian.

How long is a year on Jupiter?

A year on Jupiter is approximately 4,332 days, which is the length of time it takes for Jupiter to do 1 full revolution around the Sun.

In the 1 year (365.25 days*) it takes Earth to orbit the Sun, the massive Jupiter is only about 1/12th (8 percent) of the way. Put another way, it takes Jupiter almost 12 times as long to orbit the Sun than it takes the Earth.

FYI - Jupiter, and all other planets in our Solar System, revolve around the Sun in a counter-clockwise motion.

*An Earth year is often shown as 365.25 days, to account for leap years which have 366 days.

How long is day on Jupiter?

A day on Jupiter is short, about .41 of an Earth day, or about 9.8 hours. In fact, Jupiter's day is the shortest in the Solar System.

A day is the amount of time for a planet to make a full rotation on its axis. So while Earth makes a full rotation in 1 day, in that time Jupiter has done approximately 2.4 spins!

Would I Age Faster on Jupiter?

No, you would not age faster on Jupiter, but much more slowly.

For each 1 year you aged on Earth, you would only age about 1 month on Jupiter. But what's interesting here is that you'd have many more days on Jupiter, given its faster rotation.

So, for example, when you are 36 years old on Earth (13,149 days), you'd be just 3 years old on Jupiter - but would have had 32,071 Jovian days!

Does Jupiter Have Moons? Rings?

Not only does Jupiter have moons, currently about 90, with many of these having been discovered recently, including 12 new Jovian moons between 2021 and 2022.

Saturn has the most moons of any planet, but at one point during the recent finds, Jupiter surpassed Saturn in moon counts!

Galileo discovered Jupiter's first 4 moons in 1610: Io, Europa, Ganymede, and Callisto. Ganymede is our Solar System's largest moon. Scientists believe that conditions on Europa could support life, though to date there is no evidence of this.

While Saturn is the planet known for centuries for its rings (also discovered by Galileo), it turns out Jupiter also has rings, discovered in 1980 by Nasa's Voyger 1. However, while Saturn's rings are of ice, Jupiter's narrow rings are comprised of dust and small rocks.

Does Jupiter Have Seasons?

No, Jupiter does not have seasons like we have on Earth, primarily due to its axis being at a tilt of about 3 degrees, which means that it rotates in an almost upright position. Jupiter's axial tilt is similar to that on Venus.

But Jupiter has storms, big ones, that can last centuries. This includes the Great Red Spot, a massive anticyclone in Jupiter's Southern Hemisphere, which is larger in diameter than Earth, with winds at about 420 mph (675 km/h). Earth's strongest cyclone to date was in 2015: Hurricane Patricia, with sustaining winds up to 215 miles per hour (346 km/h).

How far is Jupiter From the Sun?

Jupiter has a mean distance of about 480 million miles (772 million kilometers) from the Sun, which is 5.2 astronomical units (AU).

If a spacecraft simply wants to flyby Jupiter, you know a little sight-seeing vacay, it would take close to 2 years to get to it. But if that spacecraft wants to go into Jupiter's orbit, that's a haul, and would take about 5.5 years.

FYI Jovian Fans - Nasa launched Europa Clipper in October 2024, which is expected to insert itself into Jupiter's orbit in April 2030! Its goal: study Jovian moon Europa. Find out more at NASA.

An astronomical unit (AU) is defined as the distance between the Sun and planet Earth, which is 93 million miles (149 million kilometers).

Has Jupiter Been Visited?

Yes, Jupiter has had several visits from orbiters, probes, and spacecraft passing by en route to other planets or places, like the Kuiper Belt. These include Jovian visits from:
