The system of longitude/latitude was developed and is used for the purpose of locating points on the Earth's surface. Rigel is a star, and its location is described by means of a similar but separate system of coordinates that applies to the 'celestial sphere'. Even if you want to talk about the point on Earth that Rigel is directly over, that point changes about every 30 seconds, and it sweeps completely around the Earth in a day.
Rigel is imagined to be one of the feet of Orion, the Hunter. That's the origin of its name "Rigel" . . . from the Sumerian/Hebrew/Arabic "regel" meaning 'foot'.
The name Rigel derives from the Arabic Rijl meaning left foot. Since Rigel represents Orion's left foot, the name seemed kind of obvious.
Rigel appears bluish-white in color, while Betelgeuse appears reddish-orange to the human eye.
The star Rigel was named by the Arabic astronomers. Rigel is derived from the Arabic word "rijl" which means "foot," as it represents the foot of the Orion constellation.

It is basically a sphere, but with a little bulge in the middle caused by its rotation.
Rigel is visible along with Orion. It can be seen in the mornings from August till October and in the evenings from November till January each year.
Well, honey, Sirius takes the crown for being the brightest star in the night sky, shining like a diamond in the rough. Rigel may be a hotshot in its own right, but it can't outshine the sass and sparkle of Sirius. So, if you're looking for some celestial bling, Sirius is the way to go.
Orion is a prominent constellation visible in the night sky during the winter months in the northern hemisphere. It is located on the celestial equator and can be seen from most places on Earth. Its distinctive shape, featuring bright stars like Betelgeuse and Rigel, makes it easy to identify.
Rigel, one of the brightest stars in the night sky, is compared to a welding torch because of its intense brightness and bluish-white color. Just like a welding torch emits a strong, bluish light when in use, Rigel shines brightly in the sky, making it a striking celestial object to observe.
Rigel is pronounced as "RYE-jell".
