My Age on Venus Calculator

About Age on Venus Calculator

This calculator translates anyone's current Earth age to their age on the planet Venus, showing whether one is older or younger on Venus. In addition, if birth date is provided, a birthday chart compares milestone ages (e.g. 5, 18, 21, 30, 50) on Earth and Venus.

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

What is Venus's Position From Sun?

Our Solar system hosts 8 planets*, and Venus is the second planet from the Sun. Venus has two neighboring planets, Mercury, first planet next to the Sun, and Earth, third planet from the Sun.

Earth and Venus are about 25 million miles (40 million kilometers) apart, which would take about 4 months to reach via spacecraft; Venus and Mercury are further apart, at about 32 million miles (50 million kilometers). These distances vary, depending on where each planet is in its orbit around the Sun.

*Pluto was the 9th planet until 2006, when it was demoted to a Dwarf Planet.

What is Temperature on Venus? (Extremely Hot!)

Venus is the hottest planet, reaching temperatures of about 868 Fahrenheit (464 Celsius) or more.

You would expect Mercury, closest to the Sun to be hotter than Venus, but its thin atmosphere does not retain the heat. By contract, Venus has an extremely dense atmosphere, which locks in the heat, causing a greenhouse effect.

What is Venus's Circumference and Diameter?

A planet's circumference is the distance all the way around its equator. Venus's circumference is about 23,627 miles (38,025 kilometers).

The diameter of a planet is the distance from one side across to the other, measured from the planet's center. Venus's diameter is 7,521 miles (12,104 kilometers).

Venus is slightly smaller than Earth: The diameter of Earth is 7,926 miles (12,755 kilometers), and the Circumference of Earth is 24,901 miles (40,074 kilometers).

When was Venus discovered?

Venus is one of 5 planets that is viewable without a telescope or binoculars, and was observed in ancient times, at least as early as 3000 BC.

Venus is named after the Roman Goddess Venus, who signifies beauty and love. It is believed this name was chosen since Venus is the brightest planet in our Solar system, appearing as an extremely bright star.

Having binoculars or a telescope will certainly facilitate viewing Venus, but keep in mind it can only be viewed in the East before sunrise, and in the West just after Sunset, due to its position between Earth and the Sun.

How long is a year on Venus?

A year on Venus is approximately 225 days, which is the length of time it takes for Venus to orbit the Sun (1 full revolution).

In the 1 year (365.25 days*) it takes Earth to orbit the Sun, slower Venus will have done 60 percent of its orbit.

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

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

How long is day on Venus?

A day on Venus is extremely long, equivalent to 243 days, longer than a Venusian year which is 225 days!

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, yonder on Venus it takes 243 times longer!

For Venus, in its 1 year (225 days) it takes to orbit the Sun, it still has not completed 1 day: it will take another 18 days into its next orbit for the day to complete.

Unlike most planets, Venus has a retrograde rotation, which means it is rotating around its axis clockwise.

Would I Age Faster on Venus?

You'd age faster on Venus than on Earth. For every Earth year, you'd age 1.63 years on Venus.

However, since a Venusian day is so long, you'd have very few days on Venus as compared to Earth. As an example, a 40 year old person would be 14,610 days old on Earth, but just 60 Venusian days old (65 Venusian years).

Does Venus Have Moons? Rings?

Venus does not have any moons, nor does it have any rings.

What Venus does have is a quasi-satellite, an asteroid named Zoozve, discovered in 2002 by Brian Skiff at Arizona's Lowell Observatory in a NASA sponsored project. While Zoozve currently revolves around Venus as it travels around the Sun, it lacks the usual gravitational pull of a moon and its planet, so eventually - in 500 years or so - Zoozve will be on its way.

Does Venus Have Seasons?

No, Venus has no seasons, due to its axis being about 3 degrees, which means that it rotates in an almost upright position. The Earth, by contrast, has a tilt of 23.5 degrees, which results in our 4 seasons as we orbit the Sun annually.

How far is Venus From the Sun?

Venus has an average distance of about 67 million miles (108 million kilometers) from the Sun, which is .72 astronomical units (AU).

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

How far is Venus from Earth

Venus is approximately 26 million miles (41 million kilometers) from Earth.

How Did Venus Change Our View of Earth?

Ptolemy (born around 100 AD/CE), an astronomer and mathematician, believed that the other planets, of which 5 were visible to the naked eye, all orbited the Earth, which was at the center of our universe and did not move.

This Ptolemic System held until astronomer Nicolaus Copernicus (born 1473) determined that Earth and the other planets orbited the Sun, in part due to observations of Venus' retrograde rotation and phases.

Galileo (born 1564), observed via telescopes he built, that the phases of Venus, somewhat similar to our moon, could only occur if it revolved around the Sun, and not a stationary Earth.

In 1632, Galileo published the Dialogue, in which he concurred with Copernicus' heliocentric theory that the Sun was at the center and Earth and the other planets moved, revolving around the Sun.

This did not bode well for Galileo, who was found guilty of heresy, for which his punishment was house arrest for the remaining 9 years of this life. It is said, that even when recanting, Galileo muttered and so it moves (as in the Earth). And, we might add, and so they were correct (as in Copernicus and Galileo).

This is really fascinating history and you can find tons of books on these topics, particularly on Galileo's life.

Has Venus Been Visited?

Yes, as of 2025, Venus has been visited by 46 spacecraft since the early 1960s. Some missions were specifically to study Venus, while others used it for gravity-assist en route to other planets while simultaneously studying as they flew by.

These include:
