"R Leporis R Leporis (R Lep), sometimes called Hind's Crimson Star, is a well-known variable star in the constellation Lepus, near its border with Eridanus. It is designated ""R"" in the chart to the right. It is a carbon star which appears distinctly red. It is named after famous British astronomer J. R. Hind, who observed it in 1845. Its apparent magnitude varies from +5.5 to +11.7 with a period of 418–441 days; recent measurements give a period of 427.07 days. There may be a secondary period of 40 years. R Leporis is too far from earth for its parallax"
"Beta Leporis Beta Leporis (β Leporis, abbreviated Beta Lep, β Lep), also named Nihal, is the second brightest star in the constellation of Lepus. ""Beta Leporis"" is the star's Bayer designation. It is also known by the traditional named ""Nihal"", Arabic for ""quenching their thirst"". The occasional spelling ""Nibal"" appears to be due to a misreading. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars.

"Lupus (constellation) Lupus is a constellation located in the deep Southern Sky. Its name is Latin for wolf. Lupus was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations, although it was previously an asterism associated with the neighboring constellation Centaurus. In ancient times, the constellation was considered an asterism within Centaurus, and was considered to have been an arbitrary animal, killed, or about to be killed, on behalf of, or for, Centaurus. An alternative visualization, attested by Eratosthenes, saw this constellation as a wineskin held by Centaurus."
"Theta Leporis Theta Leporis, Latinized from θ Leporis, is a solitary, white-hued star in the southern constellation of Lepus. It has an apparent visual magnitude of 4.67, making it bright enough to be viewed with the naked eye. Based upon an annual parallax shift of 18.88 mas as measured from Earth, the system is located roughly 173 light years from the Sun. The star made its closest approach about 1.6 million years ago when it came within of the Sun. This is an ordinary A-type main-sequence star with a stellar classification of A0 V and an age of about 207"

Such specimens began to arrive in Europe in 1522, when the survivors of Ferdinand Magellan's expedition brought them home.
