A past-full moon is in the late evening and morning skies in Gemini when December begins. Apogee is on the 4th at 404,400 km distance. The moon will pass by Regulus in Leo that day. Last quarter is the next day with the moon below the lion. The moon passes near Zavijava in Virgo on […]

This month starts with a waning gibbous moon approaching lunistice. The moon will be 28.3° north on the 2nd. See it from late evening until it sets in the daytime. Jupiter’s at opposition on the 3rd at slightly less than four astronomical units from us. The early part of this month is a great time […]

As October begins, Mars is disappearing from the evening sky. If you’re looking from about 15 to 20 degrees south of the equator, you’re getting the best view, with the planet setting around an hour after the sun and almost directly above it. You may be able to see Mars passing by Spica on Monday […]

August ends with a full moon. As September begins, the moon’s crossing the equator going north. The waning gibbous moon passes by Jupiter on the 4th. Last quarter is on the 6th when the moon passes around 9° from Aldebaran. Northern lunistice is on the 8th at 28.2° from the equator. See the fat waning […]

The best view of the evening planets this month is from the southern hemisphere, particularly about 15 to 20 degrees south of the equator. Venus is close to the horizon after sunset when August starts. Mercury isn’t far above it. And Mars is a little higher still. They’re all in Leo. Those watching from middle […]

The first of four so-called supermoons in a row is this month. On July 3, full moon will be at 11:39 Universal Time at a distance of 361,926 kilometers between the center of the earth and the center of the moon. The August 1 full moon will be closer at 357,510 kilometers. The August 31 […]

As May ended, Mercury had just been at greatest elongation and began its retreat from the morning sky. It won’t be at superior conjunction until July 1, so most sky watchers have about the first half of this month to try to spot it. The messenger planet is predicted to be at dichotomy—its semi-circle phass–on […]

For northern hemisphere sky watchers, Orion is signaling that winter is long gone. The hunter sets in the early evening. Southern hemisphere observers can take this as a sign of winter. Venus is nearby. It’s close to the star El Nath at the edge of Taurus and Auriga when May starts. Mars starts the month […]

Don’t plan on seeing Jupiter this month. April starts with the big planet retreating from the evening sky toward solar conjunction on the 11th and 12th. Coincidentally, Mercury is at greatest elongation at the same time. After marching into the evening sky, it reaches 19.5° east of the sun. At that time, the messenger planet […]

The month starts with a close paring of Venus and Jupiter. Look west as darkness begins. With binoculars you may spot Vesta nearby. In a telescope, Venus is gibbous and Jupiter has little companions called the Galilean moons because Galileo was the first to see them. Venus traverses Pisces the rest of the month, climbing […]
