Antares has a radius (not raduis) equivalent to approximately 883 solar radii.
Perhaps Antares has its own solar system.
Yes, Antares is larger than V382 Carinae. Antares is a red supergiant star, while V382 Carinae is a white hypergiant star. The size of a star is determined by its radius, and Antares has a larger radius compared to V382 Carinae.
In our solar system: the Sun. In the galaxy it's Antares, compared to Antares the Sun is the size of one pixel!!!!!!!
The star Antares is approximately 600 light years away from our solar system. See the related link for more information.
Antares (Alpha Scorpii) is a huge red hypergiant star, with a radius 800 times that of our own sun. There are some bigger stars though, such as Betelgeuse (1180 solar radii) and V354 Cephei (1520 solar radii), but the biggest known star is VY Canis Majoris, which is estimated to have a diameter between 1800 and 2100 times that of our own sun. If it were in the centre of our solar system its edges would almost reach the orbit of Saturn.
Rigel: 71 solar radiiAntares: 883 solar radii.So Antares is over twelve times larger than Rigel.See related link for a pictorial of the difference (Section 5).
Antares is around 700 times larger in diameter than Earth. This means that if you were to place Antares in our solar system where the Sun is, it would engulf the orbits of Mercury, Venus, Earth, and Mars.
It is simply not practical to get solar power from far-way stars. Sure, the light could be concentrated, but there are much cheaper ways to get energy, including getting energy from our own Sun. In the event that at some time in the future a mission goes to Antares, then they may get power from Antares, once they are close. The amount of power obtained will depend on how close they are to the star.
The length of a radius (not raduis) is diameter/2.
The radius (not raduis) is approx 60,268 km.
No, it cannot be a raduis. It cannot be a radius, either.
The radius (not raduis) is 1.25 cm.
