It is one of the smaller and less obvious constellations, with an area of 270 square degrees. Lepus (the Hare) is about the same size as Columba and rather more obvious to the eye, lying to the south of Orion. It is one of Ptolemy's 48 constellations preserved to this day / Bridgeman Images

PIX4593306: Constellations of the Little Horse, Dauphin, Fleche and Petite Fox - Constellation of Equuleus and Vulpecula - At the top right, the constellation of the Little Fox, below, the Fleche, on the left, the Dolphin; at the bottom left, the Little Horse. Equuleus (the Little Horse or colt) is a small and undistinguished constellation located about 10 degrees north of the celestial equator. It is the second smallest constellation in the sky: only Crux is smaller. It contains no bright stars, so, unlike Crux, it is difficult to find, though Delphinus is a useful guide. There is little of astronomical interest here that is accessible to small telescopes. Vulpecula, the Fox, first appears in Johannes Hevelius' atlas of 1690 and was originally called Vulpecula Cum Anser, the fox with goose, but the bird has flown and the fox is hardly obvious. The constellation crosses part of the northern Milky Way and lies just south of Cygnus. The main stars of Sagitta are also well seen here / Bridgeman Images

PIX4592024: Constellation Lievre - Constellation of Lepus - The constellation Lievre is located below the constellation Orion. On the left, the bright star Sirius. Despite the faintness of its stars, Lepus (the Hare) was known in ancient Greece, as was Orion the hunter, at whose feet it resides, inconspicuously. The hare (or rabbit) is a creature traditionally associated with the Moon, since, with imagination, the man in the Moon features can also be seen as a rabbit. This connection with Orion makes mythological sense, since the Moon was perpetually chased across the sky by the Sun and Orion is a Sun god. Lepus is a middling - sized constellation, ranking 51 in size in the modern 88. Its brightest star is Alpha Leporis (Arneb), from the Arabic al-arnab meaning 'the hare'. Also visible in the image is R Leporis, Hind's Crimson star, whose brightness varies over 5 magnitudes (100 times) over a period of 423 days. It is a carbon star and at its maximum is a fine sight in a small telescope or good binoculars / Bridgeman Images

PIX4591833: Constellations of the Indian, the Crane and Toucan - Constellations of Indus, Grus and Tucana - The southern constellation of the Indian, with to its left the constellations of the Crane (top) and Toucan. Indus (the Indian, widely taken to mean the American Indian) is a constellation devoid of bright stars in a mostly undistinguished part of the southern sky. It was created by Johann Bayer and appeared in his atlas of 1603. The reference to the American Indian comes from the constellation engraving by Bayer, which shows a figure carrying arrows; however, even if it was conspicuous, most of the constellation is invisible from the USA / Bridgeman Images
