Solar System
A star system is a group of planets, meteors, or other objects that orbit a large star. While there are many star systems, including at least 200 billion other stars in our galaxy, there is only one solar system. That''s because our sun is known by its Latin name, Sol. The solar system includes everything that is gravitationally drawn into the sun''s orbit.

When it lines up
Nebular theory and the formation of the solar system
Not only that, but our Sun is but one star among a hundred million in our galaxy, and our galaxy is one of perhaps a hundred million in the universe. So the lessons we learn by studying our own solar system can likely be applied more generally to the formation of other solar systems elsewhere, including those long ago, in galaxies far, far away.

6 FAQs about [Is the 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 the Sun a multi-star system?
Our Sun is a very average star. It’s a main-sequence yellow star that is around the middle of its lifespan. It is in the middle of the pack in terms of size too, and like most stars, it is not part of any multi-star system.
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.
Which star is at the center of the Solar System?
The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
What is the largest star in the Solar System?
The sun is a yellow dwarf star in the center of the solar system, and it is the largest, brightest and most massive object in the system. The sun formed around 4.5 billion years ago. At that time, the area of the Milky Way galaxy that would become the solar system consisted of a dense cloud of gas — the remnants of an earlier generation of stars.
How big is the Sun compared to Earth?
The Sun is about 100 times wider than Earth and about 10 times wider than Jupiter, the biggest planet. The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.
