The star Sirius has an apparent magnitude of -1.46 and appears 95-times brighter compared tothe more distant star Tau Ceti, which has an absolute magnitude of 5.69.(a) Explain the terms apparent magnitude, absolute magnitude and bolometric magnitude.(b) Calculate the apparent magnitude of the star Tau Ceti.(c) Find the distance between the Earth and Tau Ceti.www.
Star A has an apparent magnitude of –1.5 and is 12.6 light-years from Earth. Star B has an apparent magnitude of 0.4 and is 15.6 light-years from Earth.
Why should apparent magnitude NOT be used to determine which star is brighter? What information could help you determine which star is brighter?
How far away would the Sun need to be to be just visible to the naked eye (apparent magnitude = 5.90). Hint: the absolute magnitude of the Sun is 4.83. Answer in parsecs
