The star you're looking for to tell direction is Polaris, the North Star.
If you know what time it is, and have an accurate star map, you could use Betelgeuse to tell direction, but it's difficult.
Betelgeuse can be found in the constellation of Orion, which is visible in the winter sky in the northern hemisphere. Look for the bright red star in the upper left corner of Orion, forming part of the hunter's shoulder.
a comet has tail behind it while a star is like a little dot.
The group of stars known as the Big Dipper (part of Ursa Major) can be used as a star clock to tell time at night. By tracking the position of the Big Dipper in the night sky, you can estimate the time based on its orientation relative to the North Star.
Sharp shadow show us that light travels in straight lines and cannot bend around corners.
Spectrometers are used for this. By looking at the spectrum of light coming from the star, scientists can tell which elements are in the star by the pattern of lines that are known to be associated with certain elements.
You can tell if Rigel or Betelgeuse is hotter based on their color. Rigel appears blue-white, indicating a hotter temperature, while Betelgeuse appears orange-red, suggesting a cooler temperature. Additionally, the spectral class of Rigel (B8Ia) is hotter than Betelgeuse's spectral class (M1-2Ia).
Stars tell direction
The position of Betelgeuse in the sky is a function of the date and your location. I recommend the open-source planetarium program "Stellarium", which will tell you, for any location and date you specify, the location of any star or planet in the sky.
It tells the astronomer the general direction in which the star is located.

It's really hard to tell from that description, but it could possibly be a neutron star.
The simple answer is by looking at them.The technical answer is by analysing their bolometric luminosity with a bolometer.
I really do not know but I am sure the have a fan blog that will probably tell you their rout
You can't really tell they don't have set days. Just be on the look out!
mattybraps is hot and awesome if someone really knows where he lives tell me
The star is called a compass rose, which is used to tell direction on maps. the top of the star points towards the north, the left to the left to the west, the bottom to the south, and the right to the east.
