Where is the Betelgeuse star?

Spotting the Betelgeuse star should be relativity easy. First, you need to find the Orion Constellation. Often times, finding the Orion Belt, which is 3 stars forming a straight line, can help determine the constellation. The other four stars around the belt should form a trapezoid. From that, we can tell that the Betelgeuse star is on the top left corner of the constellation, forming the left shoulder of the Orion. The red giant is about 600 light years from our planet.
The exact location is:
right ascension 5 hours 55 minutes and 10.3 seconds
declination +7 degrees 24 minutes and 25 seconds

the four corner forms a rectangle shape or a trapezoid

What is the Betelgeuse?

The Betelgeuse is a red supergiant star located in the constellation of Orion. It is known as a red supergiant star because of the size and the heat it gives off. Betelgeuse is one of the largest stars in the galaxy and it emits 6,000 degree Fahrenheit of heat compared to the 10,000 degree Fahrenheit the sun gives off. Relative to other stars, this is a low temperature which gives the star an orange-red color. There are some controversy on the brightness of the star, but it is either the brightest or the second brightest in the Orion. Betelgeuse Star is also the ninth brightest star in the sky, emitting almost 100,000 times more energy than our very own sun. To add on, the red giant's name comes from Arabic which means "Armpits of the Giant"

Because of its low temperature, the Betelgeuse Star is represented in a orange-red color.
