Planet Distance to Sun
You must be wondering the planet distance to Sun. The distance between the Earth and the Sun defines the astronomical unit, which is by convention 150 million km (93.2 million miles).
Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (44,117 miles), while the farthest planet, Neptune, is approximately 30 AU from the Sun. With a few exceptions, the further a planet or belt is from the Sun, the greater the distance between its orbit and the orbit of the next object closest to the Sun.

For example, Venus is about 0.33 AU farther from the Sun than Mercury, while Saturn is about 4.3 AU farther from Jupiter, and Neptune’s orbit is 10.5 AU farther than Uranus. In the past, astronomers have tried to determine a relationship between these orbital distances, notably the Titius-Bode law, but no such theory has finally been validated.

How many years do you need to drive from the Sun to the following planets?
Good! But let’s move on to more meaningful figures: Let’s take a good car (preferably very comfortable) and travel the Solar System, say at a constant speed of 100 km/h (62.13 mp/h). Starting from the Sun, here are the necessary travel times:
- Mercury 66 years
- Venus 123 years
- Earth 171 years
- Mars 260 years
- Asteroid belt 480 years
- Jupiter 890 years
- Saturn 1600 years
- Uranus 3250 years
- Neptune 5100 years
- Pluto 6800 years
