For numerical convenience, an object brighter than 0th magnitude has a negative magnitude; the brightest star, Sirius is magnitude -1.4; the full moon is magnitude -13, and the Sun is a blazing -26th magnitude.
Venus appear as a brilliant yellow star many times brighter than any other star in the sky. It is ~18 times brighter than the brightest star Sirius (located in the southeast) and ~75 times brighter than Capella (the bright star located nearly over head in the evening).y far the brightest âstarâ in the sky during the evening hours is Venus. Though to the eye it looks like a star, Venus is actually the 2nd planet from the Sun. For the next few weeks Venus is at its brightest and highest in the sky.
