My Age on Uranus 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 Uranian age you are calculating. If calculating how old you would be on Uranus, you can leave this field empty.

About Age on Uranus Calculator

This calculator translates anyone's current Earth age to their age on the planet Uranus. In addition, if birth date is provided, a birthday chart compares milestone ages (e.g. 13, 18, 25, 40, 55) on Earth and Uranus.

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

How do you pronounce Uranus

Ok, let's get this out of the way, before seriously delving into the fascinating world of Uranus!

There are two ways to pronounce Uranus. And, yes, one is exactly the way you've heard it joked about from here to the moon and back - one of Uranus's 28 moons, that is, a billion miles away.

The other Uranus pronunciation is more refined. Hop on over to Merriam Webster to see and listen to the phonetics.

Grand. Now let's look at Uranus :)

What is Uranus's Position From Sun?

Uranus is the seventh planet from the Sun, third largest planet in our Solar System after Jupiter and Saturn, tilts at about 90 degrees, so its poles are sideways to the Sun, rotates sideways, and it has retrograde (clock-wise) rotation like Venus. And, Uranus emits a blue hue due to being partly composed of methane.

Uranus has two neighboring planets: Saturn, sixth planet from the Sun, and Neptune, eighth planet from the Sun.

The average distance from Uranus to Saturn is 900 million miles (1.4 billion kilometers).

The average distance from Uranus to Neptune is 1 billion miles (1.6 billion kilometers).

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 Uranus?

Uranus is the coldest planet in our Solar System, despite its not being the furthest. In its clouds, Uranus reaches about -435F (-224C). Brrrr.

What is Uranus's Circumference and Diameter?

Uranus is the third largest planet, with a diameter of almost 31,518 miles (50,723 kilometers). The diameter of a planet is the distance from one side across to the other, measured from the planet's center.

Uranus's circumference is 99,018 miles (159,354 kilometers). A planet's circumference is the distance all the way around its equator.

Uranus is about 4 times larger than our Earth.

When was Uranus discovered?

Uranus was discovered on March 13, 1781, by William Hershel with a telescope he hand-built. Hershel was born in Germany in 1738, but emigrated to England at age 19, where he died in 1822.

Whoever finds a planet has naming rights, so Hershel decided on Georgium Sidus (George's Planet) for his planet, to honor King George III. What's in a name you ask? Well, apparently a lot, as it was not what other astronomers felt appropriate, and in 1850, some 28 years after Hershel died, it was renamed Uranus, keeping with the tradition of naming planets after Roman Mythological gods*!

*Actually, Ouranos (alternate spelling Uranus) was the Greek god of the sky, whose Roman name was Caelus.

An interesting bit of history regards Hershel's sister, Caroline Hershel (more at Wikipedia), who lived to the age of 97 and worked with her brother for many years including when he discovered Uranus. The first woman to be paid a salary as a scientist in the UK, Caroline Hershel discovered several comets.

How long is a year on Uranus?

A year on Uranus is approximately 30,685 day (84 years), which is the length of time it takes for Uranus to do 1 full revolution around the Sun.

An Earthling who lives to age 84 will have circled the Sun 84 times, during which time Uranus has made just 1 iteration.

FYI - Uranus, 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 Uranus?

A day on Uranus is about 0.72 of an Earth day, which is 17.25 hours, so while shorter, its day length is closest to Earth's.

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 Uranus has rotated around its axis approximately 1.4 times!

Only two planets in our Solar System have retrograde rotation, meaning that they spin on their axis clockwise: Venus and Uranus.

In addition, Uranus is unique in that it rotates sideways, due to its axis being at about 90 degrees (82 degrees at one pole and 98 degrees at the other), which is believed to have occurred 3 to 4 billion years ago, after being struck by a large object. So Uranus rolled with the punches, literally, and found a way to circle the Sun!

Would I Age Faster on Uranus?

No, you would not age faster on Uranus; You would age extremely slowly on Uranus.

But, since Uranus is rotating about 1.39 times faster than earth, you'd have more days.

For example, when you are 25 years old on Earth (9.132 days), you'd be about 0.3 Uranian Years, but you would have lived more days: 9,132 on Earth versus 12,683 on Uranus.

Does Uranus Have Moons? Rings?

Yes, Uranus has 28 known moons. Six years after discovering Uranus, William Herschel found 2 moons, named Titania and Oberon. 3 more moons were found between 1851 and 1948, and all the rest were found after 1985, many by Voyager 2.

Uranus also has 13 rings, which were discovered in 1977, from Earth, by 3 researches from Cornell University, while visiting the Kuiper Airborne Observatory in Australia. What an awesome find!

The moons and rings of Uranus rotate around it vertically! That's because Uranus rotates sideways due to its tilt.

Does Uranus Have Seasons?

Yes, Uranus has 4 seasons a year, like on earth.

Since a year on Uranus is about 84 years, each Uranian season lasts about 21 years.

How far is Uranus From the Sun?

Uranus is really far from the sun: about 1.8 billion miles (2.9 billion kilometers), which is about 19.2 astronomical units (AU), meaning it is 19.2 times further from the sun than Earth.

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

Has Uranus Been Visited?

As of the mid-2020s, Uranus has had 1 spacecraft visit it, and another pass its orbit:
