July Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), for this orbit, on Sunday July 21st. At that time the Moon will be at a distance of 31.79 Earth diameters 251,954 miles (405,480 km) from the Earth.

   On the day of the apogee Moon the 19-day old waning gibbous Moon rises around midnight local time and sets later the following morning.

   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*

Waning Crescent Moon Passes Uranus

   Thursday and Friday mornings before the Sun rises look toward the eastern horizon for the 24-day old waning crescent Moon to be within about 8-9o to the west from the outer ringed planet Uranus on Thursday the 27th, and about 7-8o from Uranus but now to the east on Friday the 28th.


   Uranus has an apparent magnitude 5.84 which technically makes it naked-eye visible (in dark skies) however nearby is the thin waning crescent Moon outshining Uranus with a -11.00 apparent magnitude. Worth mentioning but not naked eye visible is the outermost of the 8 planets, Neptune, with a 7.90 apparent magnitude.

June Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), for this orbit, on Sunday June 23rd. At that time the Moon will be at a distance of 31.71 Earth diameters 251,374 miles (404,548 km) from the Earth.

   The 20-day old waning gibbous Moon rises around midnight local time and sets later that same day.

   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*

Moon – Uranus Conjunction

   Friday May 31st the 26.5-day old waning crescent Moon will be within about 4o from the outer ringed planet Uranus. Both rise around 1 hour before sunrise local time. The waning crescent Moon and Uranus will easily fit within the field of view of binoculars.
   However with two distinctly different apparent magnitudes (Moon -10.0 and Uranus 6.80) seeing Uranus will be a challenge compared to the much brighter Moon. Even more dimmer is the dwarf planet Ceres (apparent magnitude 18.67) located about 11o west from the crescent Moon.

May Moon at Descending Node

   Wednesday May 22nd the Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
   On the day of the node crossing the 17.5-day old waning gibbous Moon will be 5-7o to the west from the ringed planet Saturn. The following day, May 23rd, the 18.5-day old waning gibbous Moon will have orbited to the east side of Saturn passing within 5-6o.

April Moon at 2nd Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Sunday April 28th. At that time the Moon will more or less be at a distance of 31.85 Earth diameters 251,392 miles (404,577 km) from the Earth.

Does our Moon actually go around the Earth? 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 apogee the 24-day old waning crescent Moon will be over the southeastern horizon 1-2 hours before sunrise local time.

Moon – Jupiter Conjunction

   Tuesday morning April 23rd the 18-day old waning Gibbous Moon will be in a close conjunction with Jupiter as the two are separated by about 1o. The two should make for an interesting view as they both will very easily fit within the field of view of 7×50 binoculars.
