6 FAQs about [How far is it across our solar system]

How far does our Solar System extend?

Our Solar System extends much, much farther than where the planets are. The furthest dwarf planet, Eris, orbits within just a fraction of the larger Solar System. The Kuiper Belt, where we find a Pluto, Eris, Makemake and Haumea, extends from 30 astronomical units all the way out to 50 AU, or 7.5 billion kilometers. And we’re just getting started.

How big is our Solar System?

Our solar system is so big it is almost impossible to imagine its size if you use ordinary units like feet or miles. The distance from Earth to the Sun is 93 million miles (149 million kilometers), but the distance to the farthest planet Neptune is nearly 3 billion miles (4.5 billion kilometers).

How many astronomical units is 93 million miles from the Sun?

The Earth averages at 93 million miles (150 million kilometres) from the sun, and so one astronomical unit is equal to that number. Visualization of the solar system from the sun to the Oort Cloud. NASA Another definition for where the solar system ends is the edge of the Oort Cloud.

How do astronomers measure the size of our Solar System?

The best way to appreciate the size of our solar system is by creating a scaled model of it that shows how far from the sun the eight planets are located. Astronomers use the distance between Earth and sun, which is 93 million miles, as a new unit of measure called the Astronomical Unit.

How long does it take to reach the edge of the Solar System?

At those distances, it would take you 19 million years to complete the journey to the edge of the Solar System. Even NASA’s New Horizons spacecraft, the fastest object ever launched from Earth would need 37,000 years to make the trip. So as you can see, our Solar System is a really really big place.

How far away can a comet go from the Sun?

This material piles up into a comet-like tail that can extend 230 AU from the Sun. But the true size of the Solar System is defined by the reach of its gravity; how far away an object can still be said to orbit the Sun.
