Congrats on completing another journey around our local star! For the record, you traveled about 584 million miles (940 million Km) around the Sun at an average speed of about 66,000 mph (30 km/s). Alas, your FitBit probably didn’t even give you credit for that… 😊
This month’s constellation challenge for beginners: Orion. One of the most recognizable constellations in the entire sky, Orion the Hunter is a great reference point from which to begin surveying the winter sky. Orion’s Belt is an asterism of three bright stars in a line that is hard to miss. At a roughly equal distance above and below the belt are two of the top 10 brightest stars in the night sky — reddish Betelgeuse above and bright-white Rigel below.
This month’s telescope challenge for beginners: the Orion Nebula. There is a tiny smudge just below Orion’s Belt, forming part of his dagger, which is an enormous star-forming region. It can be seen with the naked eye, so even small telescopes will reveal it as a fuzzy little cloud (“little” because it’s 1300 light years away!). And for slightly larger scopes, look for four very luminous, newborn stars very close together at the heart of the cloud. They are in a somewhat trapezoidal arrangement and, thus, are called the Trapezium.
More celestial highlights this month:
- 2 — New Moon. We start out 2022 with some particularly dark skies (minus the Moon’s glow) — enjoy!
- 3/4 — Quadrantid Meteor Shower. With only a crescent Moon out, this should be a nice meteor shower to see from dark skies. Best seen after midnight, but, as always, no binoculars or telescope needed — just lay back and enjoy some “shooting stars”!
- 4 — Perihelion. Believe it or not, this day marks the closest that Earth will be to the Sun in 2022. Earth’s orbit is nearly a perfect circle, so our slightly varying distance from the Sun during the year has a negligeable effect on our seasons. Remember, it is Earth’s 23-degree tilt that produces its seasons.
- 7 — Mercury at its greatest elongation. We don’t get many chances to see Mercury compared to other planets (it hangs out near something called the Sun). But this evening will feature our Solar System’s fastest-moving planet at about its highest possible point above the Western horizon after sunset (still relatively low in the sky, though).
- 17 — Full Moon. This moon was named the Wolf Moon by early Native American tribes.
- Throughout January. Various launches are planned from Kennedy Space Center, though none seem to have a confirmed launch date as of the writing of this article.
Enjoy the brilliant and bountiful winter constellations and happy hunting in Orion. Wishing you and yours a pleasant journey on your next trip around the Sun.
