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.
How hot it is.
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.
It's luminosity and it's temperature.
it is the big dipper, You can use the pointers of the Big Dipper as a star clock to tell the time.
I believe the answer is, the brighter the star the more fuel it is burning
Rigel is hotter by a long way with a temperature of 11,000 Kelvin, whereas Betelgeuse is a cool 3,500 Kelvin
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!
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.
