Regulus (α Leonis) - The brightest star of the constellation. It will lead us to it with a 9-fold extended line of the front wheels of the Big Dipper to the south. Together with the stars Arcturus from the Shepherd and Spica from the Virgin, they form a kind of spring triangle. The name comes from Latin and means "little king", in ancient Babylon it even represented the star of the ruler. Sometimes we can also come across the name Cor Leonis - "heart of the lion". Regulus is also one of the four guardians of the sky, or even royal stars - they were the stars that marked the point of the summer solstice (Regulus), the spring point (Aldebaran), the winter solstice (Fomalhaut), and the autumn point (Antares) in the Persian Empire. They divided the Sun's path - the ecliptic, and thus the year into four seasons. As one of the few bright stars, it lies near the ecliptic, exactly 1.5 degrees. Therefore, there is often an occultation by the Moon and sometimes by a planet.

Denebola (β Leonis) - The brightness of the star is 2.2 magnitude and its distance from Earth is 36 light years. It is 15 times more luminous than the Sun. At a distance of almost 19 arc minutes, we can find a yellowish star with a brightness of 6 magnitude, which can even be seen with a theater binoculars.

Algieba (γ Leonis) - "The Lion's Forehead", a corrupted name of the Arabic word Al Jabha. In reality, it is a beautiful double star located 8 degrees SSW from the star Regulus, with yellow-orange components of 2.2 magnitude (about 90 times the brightness of the Sun) and 3.5 magnitude (about 30 times the brightness of the Sun) at a separation of 4.4", with a noticeable contrast that can be perceived as green. Their mutual orbital period is estimated to be 619 years. Even in 1782, when William Herschel first discovered this attractive double star, the angular separation of its components was less than 2". Since then, the separation has significantly increased and by the end of the 20th century, it reached almost 4.4".

ζ Leonis - The wide triple star, composed of stars with no mutual relationship, is ζ Leonis with a brightness of 3.4 mag. The finder shows the star 35 Leonis to the north of it and also the star 39 Leonis to the south. Both stars have a magnitude of 6 mag.

ι Leonis - remarkable binary star. Two components with magnitudes of 4.1 and 7.0 orbit each other approximately every 180 years. In 1985, they had a separation of 1.3", but they are starting to move away from each other and by the year 2000, they had already reached a separation of 1.7", making the binary star distinguishable in at least a 10 cm telescope.

54 Leonis - A binary star located on the border of the constellation Leo Minor. These two partners have magnitudes of 4.5 and 6.3. The stars are separated by 6.5", so they should already be distinguishable with a telescope with an objective diameter of at least 5 cm. The system is located 330 light-years away from Earth. In 10-15 cm telescopes and 100x magnification, it appears as an unevenly bright, colorful binary star. The primary component appears yellow-white, while the companion is bluish to greenish.

τ Leonis - Double star, easily distinguishable even with a small telescope. The primary star has a magnitude of 5.4 and its companion has a magnitude of 7.0. The angular separation between the two components is 90".

R Leonis - The variable star of Mira Ceti type is located in the western part of the constellation, near the star Regulus, at a distance of 372 light years. This red giant changes its brightness from 4.4 mag to 11.3 mag with a long period of 312.43 days. It is therefore one of the brightest long-period variable stars. At the time of maximum brightness, we can notice its distinct dark red shade, which nicely contrasts with the white star 19 Leonis, located 8' to the south.

Wolf 359 - A faint star with a magnitude of 13.7, named after Max Wolf, who worked at Heidelberg University in the early 20th century and discovered its proper motion. It moves by 4.71" annually across the sky. One of the reasons for this apparent motion is its proximity to us. It is located at a distance of only 7.86 light-years from the Sun, making it our third closest star after Proxima Centauri and Barnard's Star in Ophiuchus.
