Jupiter
Jupiter is the largest planet in the Solar System, located fifth from the sun. It has a diameter of 139,822 kilometers and a mass of 1.898 x 10^27 kilograms, making it more than twice as massive as all the other planets in the Solar System combined. Jupiter is a gas giant planet composed mostly of hydrogen and helium, with a small rocky core at its center. The planet has a banded appearance, with swirling cloud formations and a famous Great Red Spot, a persistent high-pressure storm in the planet's atmosphere that is larger than the size of Earth. Jupiter has a rapid rotation, with a day length of 9.9 hours, and it orbits the sun once every 11.86 Earth years. The planet has 79 known moons, including four large Galilean moons: Io, Europa, Ganymede, and Callisto. Jupiter has been explored by multiple spacecraft, including the Galileo mission and NASA's Juno mission, which is currently in orbit around the planet.
Jupiter is currently in the constellation of Taurus, at a distance of 901,418,799 kilometers from Earth.

Jupiter Distance from Earth
The distance of Jupiter from Earth is currently 901,418,799 kilometers, equivalent to 6.025612 Astronomical Units. Light takes 50 minutes and 6.8095 seconds to travel from Jupiter and arrive to us.
The following chart shows the distance of Jupiter from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of Jupiter from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Jupiter to Earth
Between 1 January 1600 and 30 December 2499, the closest approach of Jupiter to Earth happens on Tue Oct 16 2485 at a distance of 3.943792 Astronomical Units, or 589,982,961 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Jupiter Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Jupiter, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
