These observations were revolutionary. Copernicus and Galileo upended the long-held Aristotelian view of the heavens as a place where Earth was the center of the Universe and the Moon was a smooth, polished orb. Telescopes and new minds helped scientist understand that the Earth and planets orbited around the Sun and the Moon was a battered and cratered satellite held in our own orbit.

Phase Names. Major Phases. Northern Hemisphere. January AD Loading The next full moon will occur on Wednesday, Oct. EDT UTC , but the moon will appear full the night before and after its peak to the casual stargazer.
October's full moon is known as the Hunter's Moon among other names. Related: Night sky, October What you can see this month. If you know a youngster who can't get enough of the moon, then they'll be delighted with views through the Orion GoScope II. Revealing craters and seas up close, this little telescope comes with a carry case and moon map.
Many cultures have given distinct names to each month's full moon. The names were applied to the entire month in which each occurred. The Farmer's Almanac lists several names that are commonly used in the United States.
There are some variations in the moon names, but in general, the same ones were used among the Algonquin tribes from New England on west to Lake Superior. European settlers followed their own customs and created some of their own names.
Other Native American people had different names. He also lists them on his website, AmericanIndian. Amateur astronomer Keith Cooley has a brief list of the moon names of other cultures , including Chinese and Celtic, on his website. Full moon names often correspond to seasonal markers, so a Harvest Moon occurs at the end of the growing season, in September or October, and the Cold Moon occurs in frosty December. At least, that's how it works in the Northern Hemisphere.
According to Earthsky. The moon is a sphere that travels once around Earth every It also takes about 27 days for the moon to rotate on its axis. So, the moon always shows us the same face; there is no single "dark side" of the moon. As the moon revolves around Earth, it is illuminated from varying angles by the sun — what we see when we look at the moon is reflected sunlight. On average, the moon rises about 50 minutes later each day, which means sometimes it rises during daylight and other times at night.
At new moon, the moon is between Earth and the sun, so that the side of the moon facing toward us receives no direct sunlight, and is lit only by dim sunlight reflected from Earth.
A few days later, as the moon moves around Earth, the side we can see gradually becomes more illuminated by direct sunlight. So, if you had the Moon out in the middle of space, without any interactions, it could easily have multiple moons orbiting around it. But you get problems when you have these overlapping spheres of influence.
The strength of gravity from the Earth tangles with the force of gravity from the Moon. But further out in the Solar System, there are tiny asteroids with even tinier moons. You could imagine a massive moon distantly orbiting Neptune, and around that moon, there could be a moon of its own. NASA is considering a mission to capture an asteroid and put it into orbit around the Moon.
This would be safer than having it orbit the Earth, but still keep it close enough to extract resources. But without any kind of orbital boost, those tidal forces will eventually crash it onto the Moon.
