Thin Waxing Crescent Moon Near Venus – Mercury

   Saturday evening May 23rd look toward the western horizon for the very thin young 1.3-day old waxing crescent Moon. The Moon will be about 3-4o from the inner planet Venus and about 5-6o from the other inner planet Mercury. All three will easily fit within the field of view of binoculars and given the range of apparent magnitudes should make for a great view and even a picture.

May Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), for this orbit, on Monday 18th. At that time the 26.5-day old waning crescent Moon will be at a distance of 31.88 Earth diameters 252,028 miles (405,600 km) from the Earth.

   On the day of the apogee the thin waning crescent Moon rises about 1-2 hours before sunrise local time. Looking carefully with binoculars you may be able to see nearby 4th magnitude star 20 Ceti, one of the many stars that are part of the constellation Cetus the Whale.

   

   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*

April Moon at Ascending Node

   Monday April 27th the 5-day old waxing crescent Moon will be crossing the plane of the ecliptic moving north. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit, and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   While the waxing crescent Moon is at its ascending node further to the west, lower than the Moon, is the planet Venus.

Moon – Venus Conjunction

click on graphic to see it larger   Sunday evening April 26th, at sunset, look toward the western horizon for the 4-day old waxing crescent Moon to be about 7o from the inner planet Venus.

   The combination of the waxing crescent Moon with the brightly shining Venus will make for a good view through binoculars, albeit somewhat bright. And while you are using binoculars aim a bit lower for a look at the two open star clusters within Taurus the Bull: the v-shaped Hyades, and the tiny dipper-shaped Pleiades.

Crescent Moon and the Hyades

   Saturday evening April 25th, at around sunset, the 3-day old waxing crescent Moon will be 1-2o from the reddish star Aldebaran in the constellation Taurus the Bull. Aldebaran is the brightest star in Taurus and also the brightest star of the v-shaped open star cluster the Hyades.

   The combination of the waxing crescent Moon with the stars of the Pleiades will make for a good view through binoculars.

Saturn at Western Quadrature – 2020

saturn-west-quadrature   Tuesday April 21st, the position of the planet Saturn with respect to the Earth and the Sun places this ringed planet at what is called western quadrature. Saturn is at a 90 degree angle from us as this graphic shows. Think third quarter Moon as that is a fair comparison of the relative positions. At this position Saturn leads the Sun across the sky from east to west as the Earth is rotating, meaning that Saturn rises before the Sun and also sets before the Sun.

Saturn currently is within the constellation of Sagittarius the Archer as this graphic shows. From the northern hemisphere, looking toward the southern horizon, you can find Saturn over the southeastern horizon about midway between Mars to the east, left, and Jupiter to the west, right.

Learn a little (or a lot) about Saturn by visiting the Cassini at Saturn mission web site.

   This is a short 5 minute video I made as part of a live musical performance called “Orbit”. This is a piece from the much longer tour of the solar system performance and video and shows Saturn and some of its moons as viewed from the Cassini spacecraft that month.

An ‘Old’ April Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), for this orbit, on Monday April 20th. At that time the new Moon will be at a distance of 31.86 Earth diameters 252,563 miles (406,641 km) from the Earth.

   On the day of the apogee Moon the 27.2-day old thin waning crescent Moon will be rising about 1 hour before the Sun rises and if spotted could become a personal record for seeing an ‘old’ Moon.

   While out looking for the Moon there are several planets arranged across the southern and southeastern horizon. They are arranged west to east (or east to west) along the ecliptic, the Earth’s orbital path around the Sun, as the two graphics below are showing.

   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*
