How many Earths can fit inside Antares?

It’s bigger and heavier than perhaps 90 percent of the stars in the Milky Way. It’s so big that you could fit more than a million Earths inside it. Yet when it’s compared to some of the biggest stars of all, the Sun is a mere bit of cosmic flotsam — like a BB compared to a bowling ball.

Is it possible for planets to be in Antares?

Antares is the brightest, most massive, and most evolved stellar member of the nearest OB stellar association, the Scorpius-Centaurus Association. Antares is about 550 light-years away from the Sun. Planets can also occult Antares, though, with the exception of Venus, this hasn’t happened for millennia.

How large is the star Antares?

Antares Vitals

Official name	Antares
Mass	~12 M☉
Radius	~700 R☉
Constellation	Scorpius
Right Ascension	16h 29m 24s

Is the sun smaller than Antares?

Antares is about 604 light-years from Earth. It is 700 times the sun’s diameter, large enough to engulf the orbit of Mars, if the solar system were centered on it. Despite its size, the overall density of Antares is less than one-millionth that of the sun.

Is Antares hotter than the sun?

Antares as a red supergiant Its surface temperature is about 6,100 degrees F (3,400 degrees C). That’s in contrast to our sun’s surface temperature of about 10,000 degrees F (5,800 degrees C).

Which is bigger Antares or Betelgeuse?

Antares is a binary system, so you must be talking about Antares A. Antares A has a radius of 883 R☉. Betelgeuse is at an approximate 887 R☉ slightly larger than Antares A—though, “slightly” bigger here still means a difference in diameter of almost 5.57 million km.

Is Antares bigger than Betelgeuse?

Will Antares go supernova?

As a supergiant, Antares is considered close to its end. When it has used up its hydrogen fuel, it will collapse and explode as a supernova (sometime in the next 10,000 years).

Is Antares hotter than Sun?

Antares as a red supergiant Its surface temperature is about 6,100 degrees F (3,400 degrees C). That’s in contrast to our sun’s surface temperature of about 10,000 degrees F (5,800 degrees C). So Antares is relatively cool, and its surface temperature is relatively low. Yet the star appears very bright to us.

How many times more luminous is Antares than our sun?

Antares is a red supergiant star burning 10,000 times brighter than our own sun 550 light years away in the constellation of Scorpius. The star is the 16th brightest in the night sky, and can be seen in the Northern Hemisphere from late spring to early winter, where it shines with a variable magnitude of 0.9 to 1.8.

Is Antares bigger than Arcturus?

Antares has a diameter of ≈ 700 times that of the Sun, or about 1 billion kilometers. Betelgeuse has a diameter ≈ 1300 times that of the Sun. Arcturus is 20 times bigger than the sun.

Is Antares bigger than the Sun?

Antares is only 15 times more massive but 680 times as large as the sun. Most of that is nebulous. An interesting comparison would be density as a function of radius.

How far away is Antares from the Sun?

Due to the nature of the star, the derived parallax measurements have large errors, so that the true distance of Antares is approximately 550 light-years (170 parsecs) from the Sun.

How much energy does Antares produce?

When all wavelengths of electromagnetic radiation are considered, Antares pumps out more than 60,000 times the energy of our sun! Red Antares is similar to but somewhat larger than another famous red star, Betelgeuse in the constellation Orion. Yet Betelgeuse appears slightly brighter than Antares in our sky.

What kind of star is Antares?

Today, we know that Antares is a very large massive star – a red supergiant – in the final stages of its life. Red Antares, via Fred Espenak at AstroPixels.

When is Antares visible from the equator?

Antares is visible all night around May 31 of each year, when the star is at opposition to the Sun. Antares then rises at dusk and sets at dawn as seen at the equator. For two to three weeks on either side of November 30, Antares is not visible in the night sky from mid-northern latitudes, because it is near conjunction with the Sun.
