The second bright star is Sheratan. It is a blue-white star located 59 light-years away. Sheratan is a spectroscopic binary. This means it has a hidden companion star. You can only find this companion by studying light. The other bright stars are Mesarthim and 41 Arietis. Both of these are fourth magnitude stars.

People have looked at these stars for a very long time. The astronomer Ptolemy described Aries in the 2nd century. It is one of the 88 modern constellations we use today.

In ancient Babylon, the stars meant different things. They were once seen as a farmhand or an agrarian worker. Later, the stars became a ram. This change happened because of a connection to Dumuzi the Shepherd. The oldest records of Aries as a ram are from boundary stones. These stones date from 1350 to 1000 BC.

Many different cultures saw different shapes in these stars. In China, the stars formed a shape called 'Lou'. This means a bond or a sickle. In the Marshall Islands, people saw a porpoise.

Ancient Egyptians linked the stars to the god Amun-Ra. He was a man with a ram's head. They called the constellation the 'Indicator of the Reborn Sun'. In Greek stories, the stars were a golden ram. This ram helped a boy named Phrixus. The stars have even been called many names in Hebrew and Arabic.

Looking at Aries can help you understand how the sky changes. The Sun used to cross a specific point in Aries. This point is called the vernal equinox. It was named after this constellation.

A man named Hipparchus defined this point in 130 BC. Because the Earth moves, this point has shifted over time. It moved from Aries into Pisces. It will eventually move into Aquarius by the year 2600 AD. You can also see meteor showers near these stars. The Daytime Arietids and Epsilon Arietids come from this area. This makes the constellation a very busy part of the sky.
