Leo (Chinese Astronomy)
The modern constellation Leo lies across one of the quadrants symbolized by the Vermilion Bird of the South (南方朱雀, ''Nán Fāng Zhū Què''), and Three Enclosures (三垣, ''Sān Yuán''), that divide the sky in traditional Chinese uranography. The name of the western constellation in modern Chinese is 狮子座 (''shī zi zuò''), which means "the lion constellation".

Leo (constellation)
Leo is one of the constellations of the zodiac, between Cancer (constellation), Cancer the crab to the west and Virgo (constellation), Virgo the maiden to the east. It is located in the Northern celestial hemisphere. Its name is Latin for lion, and to the ancient Greeks represented the Nemean Lion killed by the mythical Greek hero Heracles meaning 'Glory of Hera' (known to the ancient Romans as Hercules) as one of his Twelve Labours, twelve labors. Its old astronomical symbol is (♌︎). One of the 48 constellations described by the 2nd-century astronomer Ptolemy, Leo remains one of the 88 modern constellations today, and one of the most easily recognizable due to its many bright stars and a distinctive shape that is reminiscent of the crouching lion it depicts. The lion's mane and shoulders also form an asterism (astronomy), asterism known as "The Sickle," which to modern observers may resemble a backwards "question mark." Features Stars Leo contains many bright stars, many ...

89 Leonis
89 Leonis is a single star in the equatorial constellation of Leo, the lion. It has a yellow-white hue and is faintly visible to the naked eye with an apparent visual magnitude of 5.70. Based upon parallax measurements, it is located at a distance of 88 light years from the Sun. The star has a high proper motion and is moving further away with a radial velocity of +4.8 km/s. It is a candidate member of the TW Hydrae stellar kinematic group. This is an F-type main-sequence star with a stellar classification of F5.5V. It is an estimated 1.13 billion years old and is spinning with a rotation period of 7.73 days. It shows evidence of a short-term activity cycle lasting  days. The star has 1.3 times the mass of the Sun and 1.4 times the Sun's radius. It is radiating three times the luminosity of the Sun from its photosphere at an effective temperature The effective temperature of a body such as a star or planet is the temperature of a black body that w ...

87 Leonis
87 Leonis is a single star in the zodiac constellation of Leo, located approximately 480 light years away from the Sun. It has the Bayer designation e Leonis; ''87 Leonis'' is the Flamsteed designation. This object is visible by the naked eye as a faint orange-hued star with an apparent visual magnitude of 4.77. It is moving away from the Earth with a heliocentric radial velocity of 19 km/s. The star is positioned near the ecliptic and thus is subject to occultation by the Moon. This is an aging K-type giant star with a stellar classification of , which means it has exhausted the hydrogen at its core and evolved away from the main sequence. The suffix notation indicates a mild underabundance of iron in the atmosphere. It has expanded to 37 times the Sun's radius and is radiating over a thousand times the Sun's luminosity from its photosphere at an effective temperature The effective temperature of a body such as a star or planet is the temperature of a bl ...

Upsilon Leonis
Upsilon Leonis (υ Leo) is a star in the zodiac constellation of Leo. It is visible to the naked eye with an apparent visual magnitude of 4.33. The distance to this star, as determined using parallax measurements, is about 182 light years. At that distance, the visual magnitude of the star is diminished by an estimated extinction factor of 0m.02 because of interstellar dust. With an age of around 4 billion years, this star has evolved into a G-type giant star with a stellar classification of G9 III. It has 2.6 times the Sun's mass, but has expanded to 11 times the solar radius and shines with 56 times the luminosity of the Sun at an effective temperature of 4,842 K. The rate of rotation is too small to be measured, with a projected rotational velocity of 0.0 km/s. The chemical abundance of elements other than hydrogen and helium, what astronomers term the star's metallicity, is less than half that in the Sun. It is most likely a member of the ga ...

Tau Leonis
Tau Leonis (τ Leo) is a star in the zodiac constellation of Leo. Because it is located near the ecliptic, it is subject to occultations by the Moon. It has an apparent visual magnitude of 5.00, which is bright enough to be seen with the naked eye. The distance to this star, as estimated using parallax measurements, is 560 light years. It is moving closer to the Sun with a radial velocity of −9 km/s. This G-type giant star has a stellar classification of G8- IIIa and currently resides on the red giant branch. It has about 390% of the Sun's mass. The star is much younger than the Sun, with an age of around 190 million years. As an evolved giant, it has expanded to about 25 times the Sun's radius and radiates 330 times the luminosity of the Sun. The effective temperature The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. Effective tem ...

72 Leonis
72 Leonis is a single variable star in the zodiac constellation of Leo (constellation), Leo, located roughly 1,000 light years away from the Sun. It has the variable star designation FN Leonis; ''72 Leonis'' is the Flamsteed designation. In Chinese astronomy, 72 Leonis is called 虎賁, Pinyin: Hǔbēn, meaning ''Emperor’s Bodyguard'', because this star is marking itself and stands alone in the ''Emperor’s Bodyguard'' Asterism (astronomy), asterism, Supreme Palace enclosure mansion (see : Chinese constellation). It is dedicated to the memory of Julio Cubillas, who died in December 2020, by the White Dwarf Research Corporation. This object is visible to the naked eye as a red-hued star with an apparent visual magnitude of 4.56. It is an stellar evolution, evolved bright giant with a stellar classification of M3 IIb and was listed as a spectral standard star for that class. The star is classified as an irregular variable of type LC, ranging from Hipparcos mag ...

93 Leonis
93 Leonis (93 Leo) is a binary star in the constellation Leo. Its apparent magnitude is 4.522. Based on the system's parallax, 93 Leonis is located about 233 light-years (71 parsecs) away. 93 Leonis is a double-lined spectroscopic binary. Two components are known to exist, because their spectral lines shift periodically, due to the Doppler effect. The two stars are a G-type red giant and an A-type main-sequence star. They complete an orbit once every 71.69 days. The system is also known to be an RS Canum Venaticorum variable, due to its binarity. For that reason, it has been given the variable star designation DQ Leonis. In Chinese astronomy, 93 Leonis is called 太子, Pinyin: Tàizǐ, meaning ''Crown Prince'', because this star is marking itself and stand alone in ''Crown Prince'' asterism, Supreme Palace enclosure mansion (see : Chinese constellation).
