What is the right ascension and declination of Orion?
Orion is in the southwestern sky if you are in the Northern Hemisphere or the northwestern sky if you are in the Southern Hemisphere. It is best seen between latitudes 85 and minus 75 degrees. Its right ascension is 5 hours, and its declination is 5 degrees.
What are the celestial equatorial coordinates of Betelgeuse?
Similarly, to locate the star Betelgeuse on the celestial sphere, look 5h52m east of the vernal equinox (the line on the sky with a right ascension of zero) and 7° 249 north of the celestial equator.
What is the size of Orion in right ascension?
It has a magnitude of 9.00 and an apparent size of 20.5 x 15.0 arcminutes. It is 1,400 light-years away from us and is located at right ascension 05h 36m 36s and declination -05° 16′ 00”. M78 (NGC 2068) – This bright reflection nebula has a magnitude of 8.30 and an apparent size of 8.0 x 6.0 arcminutes.
Will we see a supernova explosion in 2022?
According to study from a team of researchers from Calvin College in Grand Rapids, Michigan, a binary star system that will likely merge and explode in 2022. This is an historic find, since it will allow astronomers to witness a stellar merger and explosion for the first time in history.
Is Beetlejuice going to explode?
Bottom line: Betelgeuse is due to explode as a supernova someday, although maybe not soon on a human timescale. When it does explode, it’ll be bright enough from our earthly vantage point to shine during the day. But it’s far enough away that Earth won’t be in danger.
What planet is near Orion’s Belt?
As dusk gives way to darkness, use Orion’s Belt to locate Sirius, the brightest star in the nighttime sky, plus the star Aldebaran and the planet Mercury. From northerly latitudes, Mercury is fairly easy to catch as dusk gives way to darkness. But if you’re not sure which object is Mercury, let Orion point the way.
What star will explode next?
Betelgeuse
Betelgeuse is a red supergiant — a type of star that’s more massive and thousands of times shorter-lived than the Sun — and it is expected to end its life in a spectacular supernova explosion sometime in the next 100,000 years.
What are the coordinates of Betelgeuse?
The declination of Betelgeuse is 7° 24′ 25″. You should be able to confirm the coordinates of Betelgeuse. In addition confirm that the RA for the pointers of the Big Dipper is about 11 h with declinations near 60°. The Great Square of Pegasus is between RA 23 h and 0 h and declination 15° to 30°.
What is the luminosity of Betelgeuse?
Betelgeuse has about 140,000 times the luminosity of our sun or about 5.37×1031 watts.
Where is the star Betelgeuse?
Betelgeuse is a red supergiant star located 640 light-years away in the constellation of Orion. This distinctive star is found in the upper-left corner of Orion and marks the hunter’s right shoulder.
What is the spectrum of Betelgeuse?
Betelgeuse has a spectral type of B3V, a surface temperature of 3500° Kelvin and a luminosity 140,000 times the Sun. It has a mass of 18 solar masses and a diameter 1180 times the Sun. The image above shows the uncropped view of Betelgeuse (North is up) through the Takahashi E-180 Astrograph .
