The moon by no means seems to be precisely the identical from night time to nighttime. Its altering look is a results of its journey round Earth. That is referred to as the lunar cycle.
The lunar cycle is a sequence of eight distinctive phases of the moon’s visibility. The entire cycle takes about 29.5 days, in keeping with NASA, and these totally different phases occur because the Solar lights up totally different elements of the moon while it orbits Earth.
So, let’s examine what’s occurring with the moon tonight, Sept. 1.
What’s at this time’s moon section?
As of Monday, Sept. 1, the moon section is Waxing Gibbous, and 62% will probably be lit as much as us on Earth, in keeping with NASA’s Every day Moon Statement.
There’s tons to see on the moon’s floor tonight, so lets get into it. With no visible aids, you will see the Tycho Crater, the Mare Crisium, and the Mare Tranquillitatis. With binoculars, you will additionally get a glimpse of the Mare Nectaris, the Mare Frigoris, and the Apennine Mountains.

What are moon phases?
In line with NASA, moon phases are brought on by the 29.5-day cycle of the moon’s orbit, which adjustments the angles between the Solar, Moon, and Earth. Moon phases are how the moon seems to be from Earth because it goes round us. We at all times see the identical aspect of the moon, however how a lot of it’s lit up by the Solar adjustments relying on the place it’s in its orbit. That is how we get full moons, half moons, and moons that seem fully invisible. There are eight principal moon phases, they usually comply with a repeating cycle:
New Moon – The moon is between Earth and the solar, so the aspect we see is darkish (in different phrases, it is invisible to the attention).
Waxing Crescent – A small sliver of sunshine seems on the proper aspect (Northern Hemisphere).
First Quarter – Half of the moon is lit on the proper aspect. It seems to be like a half-moon.
Waxing Gibbous – Greater than half is lit up, however it’s not fairly full but.
Full Moon – The entire face of the moon is illuminated and totally seen.
Waning Gibbous – The moon begins dropping mild on the proper aspect.
Final Quarter (or Third Quarter) – One other half-moon, however now the left aspect is lit.
Waning Crescent – A skinny sliver of sunshine stays on the left aspect earlier than going darkish once more.
