How will the universe end?
Will the Universe end in a Big Freeze, a Big Rip – or something even stranger? Take a look into the distant future with astronomers from the Royal Observatory Greenwich.
How big is the diameter of the solar system? This article will give you the answer.

The solar system is basically the sun and its surroundings. The planets, moons, meteors, asteroids, comets and all the other matter are small pieces of the sun that orbit around it. So the sun and the things that orbit around it make up a solar system.
What is the solar system?
The solar system is a complex of giant celestial bodies orbiting the Sun, held by the Sun's gravity. These celestial bodies are called planets.
Our Earth is currently located in this region, but we are too small to be considered. Simply put, the solar system consists of the Sun holding the planets around it through gravity and these planets revolve around it in fixed orbits.
The Earth we live on is one of these planets. There are other objects in the Solar System that are retained by the Sun:
The Sun accounts for about 99.85% of the total mass of the entire solar system. It is the largest and brightest star composed of hydrogen and helium gases, with hydrogen accounting for 75% and helium accounting for only 25%.
This means that planets and other objects only take up 0.15% of the total space, so we can imagine how big the Sun is.
Interesting facts about the solar system
The Solar System is just one planetary system in the vast universe. The planetary system has the Sun at its center and eight planets in nearly circular orbits within the gravitational range of the Sun. Using our Earth as a standard, let's compare how huge the planets in the Solar System are and how far they are from the Sun.
Compare the sizes of planets in the Solar System
Of these objects, Pluto is the farthest from the Sun at a distance of 39.5 AU and the closest is Mercury at a distance of 0.4 AU.
The distance between the Sun and the Earth is 1 AU, approximately equal to 149,597,870.700 km. This is an astronomical unit of measurement for measuring distances in space.
