Besides the sun and the moon, Venus is the brightest star in the whole day, with the maximum brightness of -4.4, which is 14 times brighter than the famous Sirius (the brightest star except the sun). Venus has no satellites, so there is no "moon" in the night sky on Venus, and the brightest "star" is the earth. Because it is close to the sun, the size of the sun seen from Venus is 1.5 times larger than that seen from the earth.
