Good evening all,

Question

I am working on a PowerPoint presentation for my Astronomy class about planet Earth - my question is: What is Earth's brightest apparent magnitude (if it has one)?

I have searched every reliable source I know of (and that I come across), but I cannot seem to find a "convincing" answer. I have determined the definition of brightest apparent magnitude to be how bright a star/celestial body appears to be from Earth, so I do not see how Earth would have one - still, my teacher proposed this answer should be a number for this. I came up with an answer of either the Sun or Sirius (with their respective numbers), but that does not seem to fit the answer my teacher is looking for.

Help is greatly appreciated.
