Moonrise and moonset are times when the upper limb of the Moon appears above the horizon and disappears below it, respectively. The exact times depend on the lunar phase and declination , as well as the observer's location.
The full Hunter’s Moon will reach peak full moon phase on Thursday, October 17, on 7:26 a.m. ET, which means if you’re on the East Coast, prime viewing is in the morning just before moonset ...
The moon's orbit around Earth is not a perfect circle, writes NASA. It varies in distance, from about 221,457 miles to 252,712 miles away. That's because of the constant tug of gravity between the ...
August's full moon, known as the Sturgeon Moon, reaches peak illumination on Monday, Aug. 19. September's full moon will reach peak illumination on Tuesday, Sept. 17, just days before the start of ...
The Moon then wanes as it passes through the gibbous moon, third-quarter moon, and crescent moon phases, before returning back to new moon. The terms old moon and new moon are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the Sun and begins to wax ...
The Moon's maximum and minimum declination vary because the plane of the Moon's orbit around Earth is inclined by about 5.14° with respect to the ecliptic plane, and the spatial direction of the Moon's orbital inclination gradually changes over an 18.6-year cycle, alternately adding to or subtracting from the 23.5° tilt of Earth's axis.
December is coming to an end with a "black moon" on Monday night, Dec. 30, but those hoping to see the phenomenon will be out of luck. That's because a black moon is the term for the second new ...
The Moon illusion is the optical illusion of the Moon appearing larger near the horizon than it does higher up in the sky. It has been known since ancient times and ...
