actually, there is no definite answer. As time goes on as a star's life, the star will gradually increase in size until it expands to maximum size. Then, the star will start to shrink smaller and smaller, so there is always a different number of earths in a star.
One of the largest stars known is YZ Canis Majoris.It is a Red Hypergiant star estimated to be up to 2,100 times the diameter of the Sun.This gives us a diameter of about 2,923,200,000 km and an area of 9,183,503,644.97 km2.The earths diameter is 12,742 km and this gives an area of 40,030.17 km2.This means that it would take 229,414.53 earths to make up the area of YZ Canis Majoris.
There are many types of Dwarf stars - all with different diameters. Our Sun is a dwarf star! A typical neutron star has a diameter of about 24km our Sun has a diameter of 1.392×106 km So our Sun is about 58,000 times bigger than a neutron star.
The size of Betelgeuse is variable (it pulsates); plus, there are different estimates. But its diameter is approximately 900 times that of our Sun, which in turn is roughly 100 times the diameter of Earth (actually 109, but the data don't justify a very exact calculation), so Betelgeuse has roughly 900 x 100 = 90,000 times the DIAMETER of Earth; the ratio of volumes is that same number, cubed, or (after some rounding) about 700,000,000,000,000 times as much.
The Pistol Star is a massive blue hypergiant star located in the Milky Way galaxy. It is estimated to be about 100 times more massive than our Sun. To put this into perspective, the volume of the Pistol Star is so immense that it could fit over 7 billion Earths inside it. This calculation is based on the star's volume compared to the volume of Earth.
If the question was what is the biggest star in the universe it would be Canis Majoris, which is HUGE. We can fit 1 million Earths inside our sun, and you can fit 7 QUADRILLION Earths inside Canis Majoris!

Diameter, I assume. That would be a neutron star.
The star would take 1101 years to travel around.
Sun, the Sun is the Earths 'star'
There are many types of Dwarf stars - all with different diameters. Our Sun is a dwarf star! A typical neutron star has a diameter of about 24km our Sun has a diameter of 1.392×106 km So our Sun is about 58,000 times bigger than a neutron star.
The Sun is the Earth's closest star. Without the Sun there would be no light and no heat and life would not be able to exist on Earth.
earths moon
It would take over 7,000,000,000,000,000 (7 quadrillion) Earths to fill the volume of VY Canis Majoris, the largest star in the universe
The amount kilometers around Antares is 1,108,430,000.
Normally you would observe the star's brightness, not its apparent diameter.The star's apparent brightness ("apparent magnitude") depends on its real brightness ("absolute magnitude"), and on the distance. Similarly, the star's apparent angular diameter (which is VERY hard to measure) would depend on its actual diameter, and on the distance.
It would have to be 880,000 miles in diameter, which is the diameter of the Sun.
stars really vary in size, but our sun could fit about 13 million earths I side of it
