What is the size of Antares?

Answer 1

Antares is a red supergiant. It is approximately 800 times larger than our own Sun.

The Sun has a diameter of 1.392 million kilometers so Antares is approximately 1.113 billion kilometers. This means that about 512 million Suns would fit inside Antares.

Light would take about 1 hour to cover this distance.

Answer 3

Antares, the 15th brightest star in our sky after the sun, is a red supergiant located 604.0 light years from the solar system. (604 light speed-years) x (186,000 miles/sec- lightspeed) x (86,400 sec/day) x (365 day/year) = (604 x 186,000 x 86,400 x 365) (lightspeed-year-mile-sec-day / sec-lightspeed-day-year) = 3,542,880,384,000,000 miles ("3 quadrillion 542 trillion 880 billion" etc.) give or take a few hundred feet.

Answer 4

Antares has a radius of about 800 solar radii whereas Betelgeuse has a radius of about 1,180 solar radii.
