Moon occult Regulus: a rare February sky show

On Feb 2, 2026, a near-full Moon will pass in front of Regulus—the brightest star in Leo—creating a brief occultation visible from eastern North America, parts of Africa and southwestern Europe. In eastern North America, Regulus will disappear and reappear roughly between 8:40 and 10:05 p.m. EST (times vary by location). Regulus is about 79 light-years away with magnitude +1.4; the event is best seen with binoculars or a small telescope, though it can be enjoyed with the naked eye as the Moon covers and reveals the star in a recurring monthly sequence through 2026.

The planet Mercury will be visible in the post-sunset sky this week, appearing close to the bright star Regulus in the constellation Leo. On July 28, 2023, Mercury will be just a tenth of a degree away from Regulus, making it a great opportunity to observe with binoculars. Regulus, Leo's brightest star, is actually a quadruple star system and will soon be lost in the sun's glare. Mercury, which orbits the sun every 88 days, is usually lost in the sun's glare but occasionally becomes visible in the early evening or pre-dawn sky.

Planetary Spectacle: Mars and Regulus Illuminate the Night Sky

Tonight, stargazers can observe the Red Planet Mars shining above the blue star Regulus in the western skies shortly after sunset. To locate them, first spot the bright orb of Venus and then look just above and to the left of it to find Regulus. Mars will be just above the star, appearing as a steady orange light. Regulus, the brightest star in the Leo constellation, is actually part of a quadruple star system and rotates much faster than most stars.

July marks the final month of evening visibility for Mars and Venus, two bright planets in the night sky. Venus, the most brilliant of the two, is swiftly approaching the sun and will become harder to view as the month progresses. Mars, on the other hand, appears as a featureless dot and is sulking away. In addition, the bright star Regulus in the constellation of Leo will be in the vicinity of these planets. The moon will also interact with Mars, Venus, and Regulus on July 20, marking the last gathering of these celestial objects visible in evening skies this year.

On July 9 and 10, 2023, Venus, Mars, and Regulus will be visible close together in the night sky. Venus, the brightest point of light, will be the first light visible after sunset. With binoculars, one can see the crescent phase of Venus, as well as the white and red points of light representing Regulus and Mars, respectively. Mars will appear steady while Regulus may twinkle due to its distance. The trio will fit within a 5-degree field, with Mars and Regulus getting as close as 0.7 degrees apart.
