Leo has many bright stars, such as Regulus (伪 Leonis), the lion's heart; Denebola (尾 Leonis); and 纬1 Leonis (Algieba). Many fainter stars have been named as well, such as 未 Leo (Zosma), 胃 Leo (Chort), 魏 Leo (Al Minliar al Asad ), 位 Leo (Alterf), and 慰 Leo (Subra).
Regulus, 畏 Leonis, and 纬 Leonis, together with the fainter stars 味 Leo (Adhafera), 渭 Leo (Ras Elased Borealis), and 蔚 Leo (Ras Elased Australis), make up the asterism known as the Sickle. These stars represent the head and the mane of the lion.
The star Wolf 359, a near star to Earth (7.7 light-years), is in Leo. Gliese 436, a faint star in Leo about 33 light years away from the Sun.
The carbon star CW Leo (IRC +10216) is the brightest star in the night sky at the infrared N-band (10 渭m wavelength).How many stars are in the constellation Leo?Trillions.
These questions are impossible to answer accurately unless you specify a limiting magnitude: how faint are the stars you want to count? Constellations are defined by their boundaries on the celestial sphere. Every constellation contains dozens of stars visible to the naked eye, and trillions of stars detectable in a telescope. _Every_ constellation -- all 88 of them! The stars that are joined up by lines to form constellation figures are completely arbitrary: every chart, map, or book will connect them up differently. Please explain to your teacher that questions like this are unanswerable.
By the way, Wikipedia is one of the most credible sources of astronomical information on the internet. I've checked most of the entries for constellations and they are 100% accurate. I don't understand why teachers tell students not to use them.
