Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. With a visual apparent magnitude of −1.46, Sirius is almost twice as bright as Canopus, the next brightest star. The star is designated α Canis Majoris, Latinized to Alpha Canis Majoris, and abbreviated Alpha CMa or α CMa. Its name is derived from the Greek word Σείριος, or Seirios, meaning lit. Sirius is the brightest star in the night sky. Set a reminder to look for this striking grouping in the morning.Dog Star, Aschere, Canicula, Al Shira, Sothis, Alhabor, The gibbous moon is nearly between the Red Planet and Mars. Mars and the moon are in the western sky before sunup. For sky watchers with telescopes in the central regions of North America, the planet is near its highest arc this evening and best for seeing this long-lived atmospheric storm.įor sky watchers with binoculars or spotting scopes, the largest four Jovian satellites are visible west of the planet when the Red Spot is in the best location.īy tomorrow morning, Saturn and Jupiter set in the western sky. The spot is visible for about 50 minutes before and after the prime observing time. CST, Jupiter’s Red Spot is in the center of the planet. The colors, and their changes, provide important clues to ongoing processes in Jupiter’s atmosphere.Īt 8:57 p.m. Photo Caption – This Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet’s trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter’s turbulent atmosphere than seen in previous years. Much dimmer Uranus and Neptune are part of this planetary platter, but they are more challenging to locate. This display of the bright outer planets occurs earlier during the evening as the year progresses. Block the moon’s light with your hand as you would to reduce the sun’s glare.Īt this hour, Jupiter is about halfway up in the south and Saturn is above the southwest horizon at about the same altitude as Mars. The Red Planet is 5.2° to the lower left of the lunar orb.Įlnath is 4.3° to the left of the moon and likely not easy to see with the moon’s glare. Mars and the moon are about 25° up in the east-northeast. Two hours later, the bright moon, 93% illuminated, is farther eastward compared to this morning. Mars rises about two hours after sundown. On the night of the 30 th, the planet is closest to Earth, nearly 51 million miles away.Ĭhart Caption – 2022, November 10: Four hours after sundown, Mars and the moon are close together. This morning, it is nearly 54 million miles away. Mars is getting closer to Earth as our planet catches up with it. Mars is nearly as bright as Sirius and it continues to grow in visual intensity through this month. Mars passes the star on the 18 th, after cutting between the horns five nights earlier. Mars is retrograding, apparently moving westward compared to the stellar background, near the star Elnath, the Bull’s northern Horn. To see the dimmer stars in Taurus, use a binocular. This bright moon whitewashes the dimmer stars in the sky. At one hour before sunup, it is 7.6° to the upper right of Aldebaran, the brightest star in Taurus, and over 14° to the lower right of bright Mars. This morning, the bright moon, 96% illuminated, is about one-third of the way up in the west during morning twilight. In the US, subtract five hours for EST, six hours for CST, and so on. The Great Red Spot’s transit times, when it is in the center of the planet in the southern hemisphere: 7:05 UT, 17:01 UT Nov.
