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

You mean in terms of solar radius. In astronomy, the solar radius is a unit of length used to express the size of stars. It is equal to the current radius of the sun. The solar radius of Antares is 800 solar radius. To get the diameter the equation is 2(800 solar radius).

Answer 5

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

Both are massive compared to our Sun.

Answer 6

Antares is a red supergiant star, with a radius approximately 883 times that of our Sun. In terms of volume, it could fit around 700 million Suns within its size.

Answer 7

Antares. A "red supergiant", its diameter is estimated at 700 times that of the Sun, and it is 15 to 20 times as massive.

Answer 8

Antares is classed as a supergiant star and is about 833 times as large as our sun. It is thought to weigh about 18 times as much as our sun, and to be thousands of times as bright.

Answer 9

Antares is about 600 light years from the earth.

Answer 10

Antares's radius is: 800 / 4 R☉.
