The crescent moon will swing by Saturn on Wednesday before making a close approach to Jupiter in Thursday's evening sky.
For two nights in a row starting Wednesday (Nov. 10), you can see the moon pass by two bright worlds in Earth's sky.
The moon will be about 4 degrees from Saturn on Wednesday as the two objects reach conjunction or an event in which two celestial worlds appear close to each other in the sky. You can spot the moon and Saturn together shortly after sunset. From New York City, according to the skywatching site In-The-Sky.org, you can spot the two worlds starting at 5:01 p.m. EST or local time, and they will both be visible until 9:17 p.m.
Then comes another close encounter on Thursday (Nov. 11), when the moon and bright Jupiter will also come within four degrees of each other. You can spot the pair starting around 5:02 p.m. in New York City, where they will be visible until roughly 10:34 p.m. local time, according to In-The-Sky.org.
The moon, planets and many other worlds nearby us share a path in the sky called the ecliptic, which represents the plane of the solar system. This happy coincidence leads to opportunities throughout the year where the moon and planets come close to each other. Sometimes, the worlds line up; for example, the moon will go into a partial lunar eclipse on Nov. 19 when it passes through Earth's shadow.
Saturn and Jupiter are very bright right now, so you can see the show with your naked eye. Jupiter is at magnitude -2.4 and Saturn at magnitude 0.4. For comparison, the brightest star in the sky is Sirius (magnitude -1) and naked eye visibility is generally accepted to be about magnitude 6 in areas with little or no light pollution.
