We are doing the solar system and we have to do a stargazing word search but we have to answer the questions above it to find the words. The problem is tho is that i can't find the answer for the "5 main group of stars
There is more than one way to group stars. For example, they may be grouped by where they appear on a plot of luminosity vs. spectral class, called the Hertzsprung-Russel (H-R) diagram. They may be grouped by spectral type (of which there are 7), or some other way. The H-R diagram has 4 groups:
3. Main sequence
4. White dwarfs
Perhaps you could add black holes as a 5th group of stars. Can you tell us more about the context of the question?
