Venus is the hottest planet in our solar system with surface temperatures that can exceed 880 degrees Fahrenheit due to its thick atmosphere. There are hundreds of billions of stars in the Milky Way galaxy, and most of those stars have their planets, known as
Stars
Astronomers estimate that the universe could contain up to one septillion stars – that''s a one followed by 24 zeros. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. []

6 FAQs about [Hottest star in our solar system]
What is the hottest star in the universe?
The star designated WR 102 is the hottest known star in the universe. WR 102 is also one of the most unique stars in the universe. It is defined as a Wolf-Rayet star, which are among the largest, hottest stars in the universe. Furthermore, WR 102 contains a high amount of oxygen, adding to its uniqueness among other Wolf-Rayet stars.
What is the hottest part of the Sun?
The hottest part of the Sun is its core, where temperatures top 27 million °F (15 million °C). The part of the Sun we call its surface – the photosphere – is a relatively cool 10,000 °F (5,500 °C). In one of the Sun’s biggest mysteries, the Sun’s outer atmosphere, the corona, gets hotter the farther it stretches from the surface.
Is the Sun a big star or a small star?
The Short Answer: 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.
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.
Is WR 142 the hottest star in the universe?
WR 142 is similar to WR 102. Both are oxygen-rich Wolf-Rayet stars, two of only ten known in the entire universe. As a Wolf-Rayet star, WR 142 is one of the hottest known stars in the universe with a surface temperature of 359,540 degrees Fahrenheit (199,727 degrees Celsius).
What is the brightest star in the night sky?
The brightest star in the night sky, Sirius (also known as the "Dog Star"), has a surface temperature of about 18,000 degrees F, which gives it its bluish tinge. But there are other stars, invisible to the naked eye, which are far hotter than Sirius.
