# How far away is Jupiter now?

Last Updated: Today

As of February 25 2024, Jupiter is 496,456,209 miles (798,798,040 kilometers) away from Earth, which is about 5.33963509510654 AU.

## Where does this live distance data come from?

I source Jupiter’s distance from Earth via the Horizon JPL API. It is a free service provided by NASA’s Jet Propulsion Laboratory (JPL) that offers access to ephemeris (positional) data and related information for celestial bodies, such as planets, asteroids, and comets. The system can be accessed through various interfaces, including a web interface, a telnet interface, and an email interface.

This API contains the precise distance between Jupiter and Earth from each day of the next few hundred years.

So I simply created a system to check for today’s date, then go retrieve the accurate distance value directly from NASA’s database. The up-to-date value is then displayed on this page.

## How do scientists calculate the real-time distance between Jupiter and earth?

Scientists calculate the live distance between Jupiter and Earth using a combination of mathematics, astronomical data, and the principles of celestial mechanics. The positions of Earth and Jupiter in their respective orbits are constantly changing due to their elliptical orbits and different orbital periods around the Sun.

## Jupiter's orbital parameters

Orbital parameters describe the way objects move around in space, such as planets, moons, and satellites. These parameters include the size, shape, and tilt of the orbit, as well as the object’s position and speed within the orbit.

They help scientists understand and predict the paths of celestial bodies, which is crucial for planning space missions, observing astronomical phenomena, and monitoring satellites.

### Jupiter at opposition (list for the next 30 years)

When astronomer talks about Jupiter being at opposition,  it means that Jupiter, Earth, and the Sun are aligned in a straight line, with Earth in the middle. During this time, which lasts for a few weeks, Jupiter appears brighter and larger in the sky because it’s at its closest point to Earth in its orbit.

This planetary opposition approximately once every 13 months, or about once a year, providing astronomers and stargazers with an amazing opportunity to observe and admire the godfather planet of the solar system.

Below you can find a list of opposition dates for the next 30 years:

### Just for fun, how long would it take to reach Jupiter via different transportation means

The average distance between Earth and Jupiter is 484 million miles (778 million km), so based on that distance, I have calculated the time it would take to reach the gas giant planet at the speed of different means of transportation.

• On foot (3 mph): approximately 18,411 years
• Bicycle (15 mph): approximately 3,660 years
• Horse (galloping at 25 mph): approximately 2,196 years
• Motorbike (average speed of 70 mph): approximately 789 years
• Boat (cruising speed of 20 knots which equals 23 mph): approximately 2,374 years
• Car (60 mph): approximately 877 years
• High-speed train (322 km/h equals 200 mph): approximately 262 years
• Commercial Airplane (575 mph): approximately 95 years
• Concorde supersonic jet (1,350 mph): approximately 41 years
• SpaceX Starship (projected average speed of 16,777 mph): approximately 0.32 years (or approximately 4 months).

Please note this is only for fun and it does not reflect the reality of space travel. This is a simplification and does not account for acceleration, deceleration, or the gravitational influences of celestial bodies which would play significant roles in actual space travel.

Also, these calculations assume constant speed, which is not how actual space travel works. A real trip to Jupiter would be faster due to the spacecraft picking up speed from gravitational assists.

Bonus Fact: On average it takes about 35-52 minutes (depending on the positions of Jupiter and Earth in their respective orbits) for light from Jupiter to reach Earth.

### How far away are the other planets of the solar system?

I have developed a webpage that monitors the real-time distances between Earth and each planet of the solar system (work in progress):

I’ve been fascinated by space and astronomy from a very young age. When I’m not watching space-themed documentaries, movies or TV series, I spend most of my free time in my backyard admiring the planets and galaxies with my telescope.
