Which group of stars does Antares belong?
Antares is the most evolved star in the Scorpius-Centaurus Association, a nearby OB association, a group of stars that share a common proper motion through space. Antares is the brightest and most massive member of the group. It belongs to the Upper Scorpius subgroup of the larger association.
Is Antares a main sequence star?
Antares is a binary system. The primary star that can be seen with your unaided eye is the red supergiant; its companion — Antares B — is a smaller main-sequence B-type star of 5th magnitude. It’s visible but easily lost in the glare of its rival and requires a fairly large telescope to see.
Is Antares bright or dim?
Its brightest star, Antares (Alpha Scorpii), the 15th brightest star in the sky, has a magnitude of 1.1.
What is a fun fact about Antares?
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.
What is the red star near the moon?
Sunday: The first quarter moon occurs tomorrow, but tonight the nearly half-lit moon is near the giant red star Antares. Antares looks very similar to the planet Mars, but they cannot be confused tonight. Mars is too close to the Sun right now, so Antares is one lone bright red point the first part of the night.
Where is the biggest star located?
The largest of all The star lies near the center of the Milky Way, roughly 9,500 light-years away. Located in the constellation Scutum, UY Scuti is a hypergiant, the classification that comes after supergiant, which itself comes after giant. Hypergiants are rare stars that shine very brightly.
Is Mars the North Star?
There’s no bright North Star, and only a modestly-bright South Star, for Mars. Earth doesn’t orbit exactly upright with respect to our orbit around the sun. For both reasons – different amount of tilt, and different direction of tilt – Mars doesn’t have the same North Star as Earth.
Why is there a red star in the sky?
Mars Viewing: Planet Makes Close Approach to Earth in April Dust off your telescope and prepare for a spectacular viewing opportunity of Mars in the night sky. Mars will look like a bright red star, although it shines with a steadier light than the twinkling stars. Mars rises in the east at mid-to-late evening.
Is Antares bigger than the sun?
While Antares’ diameter is about 700 times larger than the sun in visible light, this map revealed that, as seen in radio light, the star’s atmosphere stretches even farther and is even more enormous.
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). So Antares is relatively cool, and its surface temperature is relatively low.
What is the red star in the sky called?

How big is Antares?
Antares has a radius of about 680 to 800 times that of the Sun. This gives Antares a diameter between 947 to 1.114 billion kilometers in size.
What is the spectral type of Rigel?
