Is the sun bigger than a star?
Located around 9,500 light years from Earth, and composed of hydrogen, helium and other heavier elements similar to the chemical composition of our Sun, the star has a radius 1708 (±192) times larger than our Sun’s. That is nearly 1.2 billion km, resulting in a circumference of 7.5 billion km.
What stars are the coolest?
You can tell the temperature of the star. Red stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow.
Is Sirius bigger than the Sun?

What is the most powerful star in the universe?
Magnetar
- A magnetar is a type of neutron star believed to have an extremely powerful magnetic field (∼109 to 1011 T, ∼1013 to 1015 G).
- Like other neutron stars, magnetars are around 20 kilometres (12 mi) in diameter and have a mass about 1.4 solar masses.
What is the most massive star in the universe?
R136a1
R136a1. The star R136a1 currently holds the record as the most massive star known to exist in the universe. It’s more than 265 times the mass of our Sun, more than double most stars on this list. Astronomers are still trying to understand how the star can even exist.

How big is Rigel Rigel compared to the Sun?
It is an orange-red giant with a diameter as high as 52 times the size of the Sun and is about 150 times as bright as the Sun. This star was once a part of the main sequence star group. These stars are really getting large now. 5. Rigel Rigel, the first of the supergiant stars, is about 773 light years away.
How big is the biggest star in our Solar System?
It is 4,900 light years from Earth with a diameter of 1.7 billion miles. If it were placed at the center of our Solar System, it would fill the Solar System beyond the orbit of Saturn. Because of its massive size, this star is expected to die in about 100,000 years as a hypernova.
Which is the brightest star in the night sky?
It is a little more than two times the size of the Sun which makes Sirius the brightest star in the night sky because of its proximity to our system. It is a main sequence bluish-white dwarf star similar to our Sun but brighter and hotter.
