Leo has the form of a lion. You can easily find Leo because its
head looks like a backward question mark. Also Leo is close to
the Big Dipper which you probably have already seen.
Leo's brightest star is called Regulus. Regulus means "little king" in Latin. This star is one of the brightest stars in the spring sky. Denebola, which means "lion's tail" in Arabic, is Leo's second brightest star.
The ancient Greeks and Romans saw the shape of a lion in this
constellation but the ancient Chinese saw the shape of a horse.
High in the northeast during Spring is the Big Dipper (part of
Ursa Major). Alpha and Beta Majoris, two stars in its bowl. are
called the Pointers because a line drawn through them and extended
northward points to Polaris, the North Star. If you extend the same
line in the opposite direction, you will find Leo, the Lion. Leo's
head and mane are formed by an asterism known as the Sickle which
looks as a backward question mark.
Leo's brightest star, Regulus (Latin for "little king") is one of the brightest stars in the spring. It forms the dot of the question mark. Denebola (Arabic for "lion's tail") is Leo's second brightest star.
Leo harbors a group of galaxies, two spirals (M95 and M96) and an elliptical (M105) can be found in central Leo. With binoculars, the cores of the spirals, but not their faint arms, can be distinguished. M105 appears only as a faint oval-shaped glow. Under the hindquarters of Leo, a spiral galaxy (M66) can be observed. It is nearly face-on, therefore, its disk and core are visible.
During the dry season in ancient Egypt, the lions of the desert came
close to the valley of the Nile when the river flooded, which used to
happen when the Sun was in Leo. Some have interpreted this as the
origin of the name of the constellation. The ancient Sumerians,
Babylonians, Persians, Syrians, Greeks, and Romans, all recognized
this constellation as a lion. It was seen as a horse in the ancient
Chinese zodiac, and possibly as a puma in Incan lore.

Leo's brightest star, Regulus (Latin for "little king") is one of the brightest stars in the spring sky with a magnitude of 1.4. It forms the dot of the question mark and lies at a distance of 69 light-years. Denebola (Arabic for "lion's tail") is Leo's second brightest star; it has a magnitude of 2.1, and lies at a distance of 39 light-years.
