What constellation is closest to the Libra Constellation?
I’m not sure what you mean by “closest”. The sky is partitioned into 88 constellations (regions of the sky), of which one is Libra, with no gaps in between. I will assume you mean adjacent. Along the ecliptic, which passes through Libra, is the constellation Virgo on the west and northwest. Staying on the ecliptic, are the constellations Scorpius and Ophiuchus to the east. To the northeast of Libra is Serpens Caput, the only two-part constellation in the sky. Southwest of Libra is Hydra and south of Libra is the constellation Lupus. All these regions of the sky are adjacent to Libra.
