How Far Is Jupiter From The Sun?
QUICK ANSWER
Jupiter orbits an average of 484 million miles (778 million km) from the Sun, about 5.2 times Earth's distance. Jupiter's year (one full orbit) takes about 12 Earth years to complete. Sunlight takes about 43 minutes to reach Jupiter, compared to just 8 minutes to reach Earth.
Jupiter sits more than five times farther from the Sun than Earth does. The distance is huge by Earth standards but modest compared to the outer solar system. Jupiter is the first of the gas giants, the closest of the four outer planets, and the gateway to the cold half of the solar system.
What is Jupiter's distance from the Sun?
According to NASA, Jupiter orbits the Sun at an average distance of about 484 million miles (778 million km), or 5.2 astronomical units (AU). For comparison, Earth is at 1.0 AU, Mars is at 1.52 AU, and Saturn is at 9.5 AU. Jupiter's orbit is the boundary between the inner rocky planets and the outer gas giants. Its orbit is also relatively close to circular, with an eccentricity of just 0.0489.
How long does Jupiter take to orbit the Sun?
About 12 Earth years (specifically 4,333 Earth days). Jupiter travels more slowly through its orbit than the inner planets, partly because it has farther to go, and partly because the Sun's gravity is weaker at that distance. Jupiter's orbital speed is about 29,200 mph, which sounds fast but is much slower than Earth's 67,000 mph. The combination of greater distance and slower speed is why one Jupiter year stretches over more than a decade of Earth years.
How far is Jupiter from Earth?
It varies between about 365 million and 600 million miles. When Jupiter and Earth are on the same side of the Sun (called opposition), the distance is at minimum. When they're on opposite sides, it's at maximum. Sunlight takes about 43 minutes to reach Jupiter, compared to about 8 minutes to reach Earth. Signals from spacecraft at Jupiter take roughly 35 to 52 minutes to reach Earth, depending on planetary positions.
Why is Jupiter so far from the Sun?
Because it formed there. Jupiter formed in roughly the same orbital region where it sits today, beyond the frost line where compounds like water and ammonia freeze into solid grains. The greater abundance of solid material allowed Jupiter to build up a large rocky core that attracted huge amounts of hydrogen and helium. The gas giants formed where they did because that was where the material was.
Jupiter orbits 5.2 times farther from the Sun than Earth does, taking about 12 Earth years to complete one trip around. The distance is what made Jupiter possible: enough cold material for a huge planet to form, far enough from the Sun that the gas didn't burn off. Jupiter is the king of the outer solar system, and its distance is part of what made it so big.
