An Astro 2fer

   The title may be somewhat of a U.S.A. expression but it simply means there are two Astronomy events I am writing about and have combined them into one posting. So around sunset local time on Wednesday May 3rd the waxing, or very nearly first quarter Moon, will be within a few degrees from the star Regulus in Leo the Lion. While over the western horizon the ‘Red Planet’ Mars is near the stars making up the face of Taurus the Bull – the Hyades open star cluster.

Moon Cruises Past Planets and Stars

   Over the next several evenings the Moon, as it orbits toward the east and waxes from crescent to first quarter phase will pass by several planets, dwarf planets, and star clusters. On the evening of February 5th the Moon will be close to the reddish star Aldebaran, the ‘eye’ in the face of the angry bull, Taurus. This should make for a nice view with binoculars or low power eyepiece when the Moon will sort of overlay the stars of the open star cluster the Hyades.

   These two animated graphics show the sky as viewed from Quito Ecuador at 0o latitude, and my home latitude of approximately 40o North. They show the sky at one day intervals starting with February 1st and ending with February 5th.

   Sunday January 8th the 11 day old waxing gibbous Moon will be a few degrees from the nose of Taurus the Bull, and the stars making up the open star cluster the Hyades.
8jan-bino  Through 7×50 binoculars the stars of the open star cluster the Hyades and the Moon will make for an interesting sight.

December Perigee Moon Hits the Bull’s Eye

14dec-perigee_moon   The Moon reaches perigee, (minimum distance from Earth), this month on Monday December 12th. At that time the Moon will more or less be at a distance of 28.1 Earth diameters (356,509 km or 221,524 miles) from the Earth.
   Does our Moon actually go around the Earth as this graphic shows? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*
   On the day of the lunar perigee the 13.5-day old waxing gibbous Moon rises at around sunset local time and is over the southwest horizon at sunrise the following morning. The Moon is also very close to the star Aldebaran in the v-shaped open star cluster making the face of Taurus the Bull, the Hyades. Depending on your location this may be an occultation of the star by the Moon, or a very close conjunction. Nonetheless with binoculars or a wide field telescope eyepiece the Moon superimposed on the Hyades should make for great viewing.
