# How old would I be on Mercury if I was 12?

That is 4,380 days if you are precisely 12 years old (12 x 365). It would also imply that it is your birthday today. If you lived on Mercury and had a birthday every 88 days, you'd be 49.77 years old (4 380/88 = 49.77).

It's important to remember that on other planets and stars, we would be older or younger than on Earth. On Mars, for example, you would be about 38 years old (if it was your birthday today). On Venus you would be about 8400 days old (if it was your birthday today).

The Sun also lives longer than the average star. According to NASA, its lifespan is about 10 billion hours (or 584 million years) while most stars live only between 10 and 20 billion hours (or 580 million and 1190 million years).

On average, stars burn through their fuel more quickly than the Sun will when it reaches the end of its life. The majority of stars explode as supernovas after using up all their hydrogen fuel, while the Sun will go through all its hydrogen before turning into a red giant phase and then a white dwarf.

Stars are usually not exactly like the Sun. They tend to be bigger and hotter. A star like our Sun may be small compared to some others, but it still burns hot enough to be visible from far away.

## How old would you be if you were 17 on the Moon?

Since you are 17, becoming 17 on the Moon would take 459 days, or 1 year and 3 months on Earth. If your birthday is today and you are 17, you are 6205 Earth days old. You would be 229 years old if you lived on the Moon. (6205/27).

To figure out how old you would feel on the Moon if you were born on July 2nd, find the number of days between your birthday and July 2nd. Divide that by four; then multiply that number by 365 to get the estimated age you would feel on the Moon.

If you were born on July 2nd, find the number of days between your birthday and July 2nd.

For example, if you were born on August 21st, your date of birth is between July 22nd and August 22nd; therefore, the number of days between your birthday and July 2nd is 105. That's less than four weeks so you would feel young on the Moon. If you were born on January 1st, your date of birth is between December 30th and January 1st; therefore, the number of days between your birthday and July 2nd is 364.

## How long is a year on Mercury?

There are around 88 Earth days left. The day is almost as long as a Earth day, but the night is very short. Only about 4 hours of darkness!

Mercury has only two seasons: hot and cold. Ice caps cover most of the planet, except where they're not found underground in deep craters. Average temperature: -180 degrees C during the cold season, +50 degrees C during the hot season.

The cold season lasts for about 9 years, followed by the hot season for about 8 years. After these 12 years have passed, another ice age will begin to build up again.

It's hard to say how many days there are in a Mercury year because it keeps shifting when the sun does. But we can make an estimate. The average distance between planets in the Solar System is about 150 million miles (241 million km). So Mercury takes 87 Earth years to orbit the Sun. This means that it takes it 72 Earth days to go around once.

## How old would you be if you were on Pluto?

Unlike Mercury, which takes around 88 days to circle around the sun, Pluto takes about 248.59 earth years to complete one revolution. This effectively indicates that a person aged 249 years on Earth would be just 1 year old on Pluto if we use the Earth's age calculation methodology. If we assume that life can be sustained for a fraction of the time it takes on Earth (which is possible but unlikely), then Pluto would have to be born with all the water it could drink and all the air it could breathe.

Our knowledge of astronomy when Pluto was discovered in 1930 was quite limited. Scientists knew then that planets orbit the sun, but they didn't know how many planets orbit the sun. So using today's knowledge we might estimate that there must have been at least seven other planets inside Pluto's orbit at the time. The fact that we now know of only eight such bodies confirms that our estimation of their number back then was very rough.

The idea of another planet inside Pluto's orbit being suspected by astronomers already seems strange today. But in the early 1930s this wasn't known yet. So the discovery of Pluto was not only important because it revealed that there are more objects beyond our solar system than previously thought, but also because it showed that some of these objects have characteristics similar to those of Earthlings' favorite dwarf planet.

Pluto has many features that are either unique or common with Earth.

## What is my age on other planets if I was born in 1983?

From 1983 until 2020, there will be 37 years. If I was born in 1983, what is my age on other planets?

My answer: I'm a young adult on Earth and other planets. My age is calculated from the time I was born - March 18th - and including any leap years. So my age will always change because the number of days in a year varies over time.

Here's how many days I have been alive: 243,261,267. That's not very long compared to some people!

The short answer is that your age will change every day because the length of a day changes. But an average would be about 9.9 minutes per day. So you could say that my approximate age is 45.9 years old.

I hope this helps you out!

## How old are the planets in the solar system?

In the solar system, your age is: On Earth, you are 24 years old. You are 99.59 years old on Mercury. You are 39.02 years old on Venus. You are 12.76 years old on Mars. You are 2.02 years old on Jupiter. You are 0.81 years old on Saturn. You are 0.29 years old on Uranus. You are 0.15 years old on Neptune. You are 0.1 years old on Pluto.

These are the only planets that exist in our solar system today. But over time, many other objects from asteroids to moons may have passed between Earth and the Sun, causing planetary systems to evolve.

Planetary evolution occurs when a planet either loses most of its mass or changes its orbit enough for gravity to cause the surface materials to run out. The result is that one day it will be no more than a frozen rock with no gravity!

The solar system was probably not always like this. In fact, all the major planets were likely once part of a single object called "Planet X." As this object crashed into the Sun, it created a large cloud of debris that ended up forming the planets we know today.

Over time, additional material was accreted by the planets, changing their sizes compared to today. The largest moon in our solar system is Jupiter, but originally it was much closer to Earth as part of Planet X. Over time, Jupiter's gravity pulled most of the material towards it, leaving a smaller Earth behind.
