Facts about the Sun
- The Sun accounts for 99.86% of the mass in the solar system.
- Over one million Earth’s could fit inside the Sun.
- One day the Sun will consume the Earth.
- The energy created by the Sun’s core is nuclear fusion.
- The Sun is almost a perfect sphere.
- The Sun is travelling at 220 km per second.
How are suns formed?
The Sun formed about 4.6 billion years ago in a giant, spinning cloud of gas and dust called the solar nebula. As the nebula collapsed under its own gravity, it spun faster and flattened into a disk.
What are the three features of the Sun?
The main regions of the Sun include its interior, surface (photosphere), and atmosphere.
What is special about our sun?
Compared with the billions of other stars in the universe, the sun is unremarkable. But for Earth and the other planets that revolve around it, the sun is a powerful center of attention. It holds the solar system together; provides life-giving light, heat, and energy to Earth; and generates space weather.
What are 3 physical features of the sun?
Some features of the Sun’s surface include sunspots, solar flares, and prominences.
What is the job of the sun?
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
What is the temperature of the sun?
5,778 K
Sun/Surface temperature

Is the Sun a star or planet?
Yes, the Sun is a star, just like any other star you can see at night. The difference from our perspective is, that the Earth is a planet that orbits the Sun, so the Sun is much, much closer than the other stars and therefore seems brighter and larger. We now know that there are planets orbiting other stars as well,…
