The moon makes its shut method to Jupiter on Wednesday (Feb.22) with the 2 celestial objects additionally sharing the identical right ascension within the afternoon sky, an association known as a “conjunction.”
In keeping with In the Sky (opens in new tab) from New York Metropolis the conjunction between the 2-day-old waxing crescent moon and the solar system’s largest planet will probably be seen quickly after the just about new moon rises at 08:12 EST (1312 GMT). The conjunction will probably be seen till round 8:38 p.m. EST (0138 GMT).
In the course of the conjunction, the moon will probably be within the constellation Cetus whereas the huge gas giant planet Jupiter will probably be within the constellation Pisces. The crescent moon will probably be fairly vibrant with a magnitude of -10.2, whereas Jupiter can have a magnitude of -2.1. The minus prefix earlier than the 2 magnitude values signifies notably vibrant objects over Earth.
If you cannot make it outdoors to view the spectacle your self or if circumstances aren’t proper, you are in luck: the Digital Telescope Mission is internet hosting a free telescope livestream of the occasion beginning at 2:00 p.m. EST (1900 GMT).

Each the moon and Jupiter with have a right ascension of 00h39m10s in the course of the conjunction, whereas the moon has a declination of +01°49′ and Jupiter a declination of +03°00′.
Even though the objects will make an in depth method, technically often known as an appulse, the moon and Jupiter will not be shut sufficient to be seen within the slender subject of view of a telescope. The conjunction will probably be seen within the wider subject of view of binoculars, nevertheless.
Conjunctions between the moon and Jupiter happen roughly as soon as a lunar cycle, however the gas giant is not the one planet within the solar system to often meet up with the moon. Earth’s essential pure satellite strikes quickly alongside an imaginary line within the sky over the planet known as the ecliptic. The elliptic carries the moon previous the constellations and the planets of the solar system, leading to lunar conjunctions with the solar system planets that occur round as soon as a month.
Photo voltaic system planets may share the identical right ascension, being they are often in conjunction to one another, however these planets transfer way more slowly alongside the ecliptic conjunctions between the planets are far rarer than conjunctions with the moon.
One notable instance is the conjunction between Jupiter and its fellow gas giant Saturn, often known as a “nice conjunction.” Such a planetary conjunction occurs solely round as soon as each 20 years, and through a fantastic conjunction, Jupiter overtakes Saturn in its orbit.
Some planetary conjunctions are even rarer than this, nevertheless. For instance, conjunctions between Uranus and Neptune happen solely as soon as each 171 years, in keeping with In the Sky (opens in new tab). It’s because these two distant ice giants take 84 years and 165 years, respectively, to finish a visit across the sun.
The following planetary conjunction for Jupiter is on March 2, 2023, when it meets up with Venus, the second planet from the sun.
