How big is the Solar System?
Under this definition, the solar system is truly gigantic. One light year is equivalent to 5.88 trillion miles (9.46 trillion kilometres), and so the solar system would be trillions of miles in size. The size of the solar system is dependent upon what definition you use, which can range from 11 billion miles to over five trillion miles.
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.
What is the largest planet in the Solar System?
Our solar system's largest planet is an average distance of 484 million miles (778 million kilometers) from the Sun. That's 5.2 AU. Jupiter is the largest of the planets, spanning nearly 1.75 millimeters in diameter on our football field scale. Jupiter's diameter is about equal to the thickness of a U.S quarter in our shrunken solar system.
How big is the Sun?
On this scale, the Sun, by far the largest thing in our solar system, is only a ball about two-thirds of an inch (17 millimeters) in diameter sitting on the goal line — that's about the width of a U.S. dime coin. Considering a typical honeybee is about half an inch long, the fans are going to need telescopes to see the action.
What is a small body in the Solar System?
Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body; these include asteroids, meteoroids, and comets. Most of the more than one million asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt.
How long will the Solar System last?
The Solar System will remain roughly as it is known today until the hydrogen in the core of the Sun has been entirely converted to helium, which will occur roughly 5 billion years from now. This will mark the end of the Sun's main-sequence life.

How Big Is The Solar System?
Our Solar System is staggeringly big in human terms. If you look through a small telescope at the bright shape of Saturn, you will see a planet that is well over a billion kilometres away. To travel that distance on Earth, you’d
Solar system | Definition, Planets, Diagram,
There are eight planets in the solar system. The four inner terrestrial planets are Mercury, Venus, Earth, and Mars, all of which consist mainly of rock. The four outer planets are Jupiter, Saturn, Neptune, and
How big is the Solar System?
How big is the Solar System? Short answer: The Solar System is a disc shape, 244 astronomical units wide (244 times the distance from the Sun to the Earth, or about 36.6 billion km).
How Big Is the Solar System?
The far edge of the Oort Cloud is considered the edge of our Solar System, making our cosmic neighborhood quite big indeed. So, to find how big the solar system is across, we could double that distance, giving
How big is the Solar System?
Our solar system consists of 4 inner planets ( Mercury, Venus, Earth and Mars ) and 4 giant planets (Jupiter, Saturn, Uranus and Neptune ). There are also several dwarf planets ( Pluto, Ceres and Eris are just a few

To give you an idea of how big that is, 1 AU is the average distance from the Earth to the Sun, which is about 93 million miles (150 million kilometers). So, the solar system is about 100,000
