M104 (Sombrero Galaxy)
M13 Hercules Globular
M13, the “Great Globular Cluster in Hercules” was first discovered by Edmund Halley in 1714, and later catalogued by Charles Messier in 1764. It contains 300,000 stars, and is 22,000 light-years away. Light would need over a century to traverse its diameter.
The little open cluster M67 appears near its larger buddy, M44 The Beehive Cluster. These clusters are actually about the same size, but M67 is five times farther away. M67 is old for an open cluster; its stars are four billion years old.
NGC 3242 (Ghost of Jupiter)
Jupiter is the largest planet in the Solar System, a “gas giant” 11 Earth-diameters across. Its atmosphere contains the Great Red Spot, a long-lived storm 2-3 times the size of the Earth. The 4 large Galilean satellites and at least 63 smaller moons orbit Jupiter.
The same side of the Moon always faces Earth because the lunar periods of rotation and revolution are the same. The surface of the moon is covered with impact craters and lava-filled basins. The Moon is about a fourth of Earth’s diameter and is about 30 Earth-diameters away.
Algieba (γ Leo)
Algieba (γ Leonis) is a binary star in the mane of Leo, the lion. These two golden-yellow giant stars are about 23 and 10 times the diameter of the Sun, and are about 130 light-years away. Their orbital period is over 500 years. In 2009, a giant planet was found orbiting one of these stars.
