The moon and 3 planets are going to gather this week. They will form a fetching triangle in the night Sky between the evenings of Saturday to Thursday (Oct 9, to Oct 14).
The moon will visit not one but three planets for the first time. Venus will be the nearest to Earth. They will be in the “claws” of the constellation Scorpius in October 2021.
Moon And 3 Planets: Forming The Triangle
Moon and Venus would be nearer in the constellation Scorpius. On the other side, Saturn and Jupiter encounter them after five nights.
Thus the moon will be in the midway between Saturn and Uranus. They will meet on Thursday evening (Oct 14). This will form a broad and inverted Isosceles triangle. Saturn and Jupiter will make a base angle with 15 degrees in length. However the moon will mark the vertex angle.
View of Moon And 3 Planets At Night Sky
The view of this moon will be interesting on Saturday evening. The age of the moon will be about 4 days. Thus the illumination would be about 16%. It can be seen through binoculars and also through naked eyes.
Using a telescope, having lower optical power can make a clear vision of details on the lunar surface.
However, the Moon is the nearest neighbour of earth, almost 234,700 miles from earth. At the same time Jupiter and Saturn are farther enough from Earth about millions of miles. But this week, these all could be seen making a stretching triangle between them.
Moon And The Venus (The Brightest Planet)
Venus will be the moon’s partner this evening. It is the brightest of planets. Brightening at a magnitude of about -4.3. It has a higher radiance than both Jupiter and Saturn.
Venus would be nearly visible at that time. Anyone can see it slightly below the moon (for the viewers at mid-northern latitudes). It is going to become an interesting view in Telescopes because it will change in phase from nearly 60% illumination.
Thus, Venus will be the point of attraction in the coming days and weeks. Because Venus is to grow in prominence earlier in the evenings. Hence, it will be an evening object for about five months.
Moon With The Saturn
Saturn and Jupiter will meet the moon after some 4 days on the following thursday. There are some specifics of all the gatherings.
Saturn will be at the upper right of the moon. It is like a non-twinkling “star” having a yellowish-white glow. However the distance between the moon and Saturn will be about 9 degrees. Thus, a telescope with more than 30-power can show a clear dramatic view.
Moon And The Jupiter
As opposed to Saturn, there is the planet Jupiter at the upper left of the moon. It has a shining silvery glow. However it is the 2nd brightest planet in the solar system.
Jupiter will reign in the sky just past 2 in the morning. However it encounters the moon at about 8 to 10 p.m in the night sky. The vision will be quite possible at that time.
Thus anyone can see Jupiter through a small microscope or binoculars on Thursday evening. Jupiter along with its four Galilean moons will be the part of attraction in the telescope. As these moons are to change their direction every hour.
Moreover when viewing Jupiter with the telescope, there is clear insight to the four satellites. Callisto and lo satellites are on one side of the moon, while Ganymede will be on its other side. However the satellite Europa is to encounter the front of Jupiter.
