6 FAQs about [Is sun the only star in our solar system]
Is the Sun a star?
Our Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.
Is our Sun a big star?
Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system.
How many stars does our Solar System have?
Our solar system has only one star, called the Sun. The Sun is one of 100 to 400 billion stars in our galaxy, the Milky Way. Our galaxy, in turn, is one of over 100 billion galaxies in the known universe. Ask your own question! Our solar system has only one star, called the Sun.

Is the Sun a dynamic star?
From our vantage point on Earth, the Sun may appear like an unchanging source of light and heat in the sky. But the Sun is a dynamic star, constantly changing and sending energy out into space. The science of studying the Sun and its influence throughout the solar system is called heliophysics. The Sun is the largest object in our solar system.
How many suns are in a solar system?
Our Sun is a little unusual because it doesn't have any friends. It's just one Sun surrounded by planets, asteroids, comets, and dwarf planets. But solar systems can have more than one sun. In fact, that's often the case. More than half of all stars are in multiple star systems. That means the solar system has two or more suns in it.
