What is the dimmest star in the constellation Leo?

I am doing my science project and i found the brightest star but i need the dimmest star.|||The dimmest star would be one so dim that we can't see it even with the best telescope, and therefore one that has never even been discovered. If you don't limit the stars to those in this galaxy it would certainly be some small insignificant star in some distant galaxy in Leo that in itself is only a faintly discernible smudge even with the best telescopes.





As for an example of a dim star, I have the complete Tycho-2 star catalogue loaded onto this computer. A quick browse revealed the imaginatively titled Tycho 1431-1042-1 at a lowly magnitude 12.68. That certainly isn't the faintest star known - the Hubble guide star catalogue goes much fainter than Tycho-2 for instance, but that star is already over 250 times too faint to see with the naked eye under even the darkest sky.|||this question cannot be answered. define "dimmest" - dimmest to the naked eye? under what skies? dimmest in binoculars? dimmest in a telescope? dimmest in a long-exposure photograph?





i have access to a couple of observatory-quality observing sites, and the dimmest star i can see in leo out in the country is a lot dimmer than what i can see in teh city.|||Dimmest?





You're not going to fight the right answer to that here, or anywhere. Simply because nobody knows. Take a look at the night sky one day. You'll see stars. Take a look at it through binoculars, you'll see dimmer stars. Take a look at it through a telescope. You'll see stars too dim to be seen in the binoculars. Go online and get a Hubble Space Telescope view of some part of the sky. It'll show stars too dim for your telescope to see.





My point is, there are always dimmer stars. There are even stars too dim for Hubble to see. The dimmest star should be a star at the back of the farthest galaxy in Leo. (and for galaxies at the edge of the universe, even seeing them is a challenge, not to mention their individual stars).|||The star Dinklebinkbink is a 0.1 solar mass red dwarf star on the other side of the universe. It's apparent magnitude is +54, and it is the dimmest star in the constellation Leo.|||In the constellation of Leo the dimmest star would appear to be Algeiba which would be on the top of the lion's head. The absolute magnitude of Algeiba is 0.1 and is 190 light years from planet Earth.|||i take the earlier statement back. i was incorrect (yes i am man enough to admit).





the star is Wolf 359





hope this helps. http://en.wikipedia.org/wiki/List_of_sta鈥?/a>|||This question can't be answered. It depends on what imits you set. Dimmest naked eye? Dimmest with a large telescope visually? Dimmest photographically. _Think_ before you ask a question like this!
