Our solar system sun

Sun

Eventually, the gases heated up enough to begin nuclear fusion, and became the sun in our solar system. Other parts of the molecular cloud cooled into a disc around the brand-new sun and became planets, asteroids, comets, and other bodies in our solar system. The sun is about 150 million kilometers (93 million miles) from Earth.

Such volatility is contained thanks to the sun''s tremendous gravity. It''s strong enough to hold the solar system intact, and is primarily due to the sun''s size and mass. Our sun is the largest and most massive object in the solar system. It''s more than 100 earths wide, and could theoretically fit all eight planets inside nearly 600 times.

How Big Is the Solar System?

The Sun''s gravity holds our entire solar system together. Our solar system is even named after the Sun (the Latin word for Sun is "sol"). Heat from the Sun makes Earth warm enough to live on. Without light from the Sun, there would be no plants or animals—and, therefore, no food and we wouldn''t exist.

Our Solar System

Our Solar System was formed 4.568 billion years ago out of a huge cloud of gas, mostly hydrogen and helium, and a small proportion of "dust". Most of the hydrogen and helium has been used to form the Sun, but it's that small amount of dust that has made the difference for all life on Earth!

What Is the Solar System?

Solar System Formation. The solar system is located in one of the spiral arms of the Milky Way galaxy. It was born about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed. Most of the material was pulled toward a central point: nearly all of the solar system''s mass—99.8%—is in the Sun.

Meet the Sun

The Sun is a yellow dwarf star at the center of our solar system. Earth and all other objects in our solar system orbit around the Sun due to gravity – the Sun contains over 98% of all mass in the solar system and so exerts a strong gravitational pull. Like other stars, the Sun is a dense ball of gas that creates energy through nuclear fusion

Sun Facts: Interesting Facts about Sun (or Sol)

The Sun is the star at the center of our solar system. It is a big ball of gas and plasma that generates its own energy through nuclear fusion in its core. As our one and only star, it is the only natural source of light in the entire solar system. The planets, dwarf planets, asteroids, comets, and other objects in the solar system orbit the
