Planets visible to the naked eye

From January 25 to February 8, 2021

Mercury is visible in the evening sky where it’s undergoing a very good apparition until January 31: Look for Mercury a few degrees above the southwest horizon, 30 to 45 minutes after sunset. At the beginning of February, the tiny planet vanishes in the glare of the sun and passes in inferior conjunction (between Earth and the sun) on February 8.

Venus is too close to the sun and is not currently visible. The planet passes on the far side of the sun (superior conjunction) on March 26, and will gradually reappear as the bright Evening Star after mid-April.

Mars is receding from Earth, but it’s still remarkably bright. The Red Planet appears at dusk about 60 degrees high in the south and sets in the west-northwest after 1:00 a.m. During the evening of February 18, the thick crescent Moon comes within 3½ degrees to the south of Mars.

Jupiter is now too close to the Sun and is lost in our star’s glare. The Giant Planet passes behind the Sun (conjunction) on January 28 and will reappear at dawn in late-February.

Saturn is now too close to the Sun and is lost in our star’s glare. The Ringed Planet passed behind the Sun (conjunction) on January 23 and will reappear at dawn after mid-February.
