Consider a relatively nearby, single star, that is, a star that is not a member of a binary system and has no known orbiting planets. Listed below are a few properties of this star. Classify each property as either something that we can observe or measure directly (with the aid of a telescope and instruments such as cameras or spectrographs) or something that we must infer indirectly (and hence is correct only if all of our assumptions are correct).-color
-parallax angle-radius
-luminosity
-mass-spectral type
-apparent brightness-surface temperature

Answer & Explanation:

Properties we can Observe/measure           Properties we can directly Infer

color                                                                 luminosity

parallax angle                                                  surface temperature

spectral type                                                    mass

apparent brightness                                        radius
