In astronomy, the Pleiades , or Seven Sisters (M45), is an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years.

Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Jupiter was known to astronomers of ancient times. When viewed from Earth, Jupiter can reach an apparent magnitude of −2.94, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky after the Moon and Venus.

Vega is the brightest star in the constellation of Lyra, the fifth brightest star in the night sky and the second brightest star in the northern celestial hemisphere, after Arcturus. It is a relatively close star at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood.
