Supermoon 2016: The brightest supermoon in almost 70 years rises tonight

Special Supermoons
A supermoon, which appears up to 30 percent brighter and 15 percent larger than other full moons. That's because the full moon — in which the sun, moon and Earth are approximately aligned and the sunlit face of the moon is facing Earth — occurs at the spot in the moon's orbit when our satellite is closest to our planet. Because of that closeness, the full moon appears brighter and bigger than normal. Sometimes an extra-special occurrence makes this bulging supermoon even more spectacular. That occurrence is the total lunar eclipse, when the moon moves behind Earth's shadow. Check out these spectacular images of supermoons and eclipsed supermoons

The November "supermoon" is extra close to earth today (Nov. 14), providing an extraordinary sight for skywatchers — but exactly what makes this month's full moon so special?
November's supermoon —a term used to describe a full moon is at its perigee, or closest point to Earth during the lunar orbit — will be the biggest and brightest to rise in almost 69 years. In fact, the full moon won't come this close to Earth again until Nov. 25, 2034.
To help explain the science behind supermoons, and what makes the November supermoon particularly special, Space.com spoke with NASA's Noah Petro, deputy scientist of the Lunar Reconnaissance Orbiter mission

Changing Tides
By definition, a supermoon "is the one closest full moon of the year," Petro told Space.com. The distande between the moon and the changes because the moon does not orbit in a perfect circle.
"The main reason why the orbit of the moon is not a perfect circle is that there are a lot of tidal, or gravitational, forces that are pulling on the moon," Petro explained, adding that the gravity of the Earth, sun and planets of our solar system all impact the orbit of the moon. "You have all of these different gravitational forces pulling and pushing on the moon, which gives us opportunities to have these close passes."

What's more, the surface of Earth is about 70 percent ocean, which not only affects the moon's orbital pattern, but in turn creates tidal variations on Earth. This year, slightly higher tides are expected in relation to the Nov. 14 supermoon, although this is nothing unusual for close full moon approaches, Petro said.
"One of the interesting things about the moon is that it's not only pulling on the Earth's oceans, it’s actually pulling on the Earth's crust," Petro said. "The Earth's crust — the land beneath our feet — actually deforms and responds to the moon" in a very subtle way.
Supersized Moon

Supermoons can appear 30 percent brighter and up to 14 percent larger than typical full moons.

In January of 1912, the full moon was "just under 100 kilometers closer than the full moon" tonight and the supermoon of November 2034 will be even closer, Petro said.
Rare Sight
The November supermoon reaches perigee this morning (Nov. 14) at 8:52 a.m. EST (1352 GMT). When the moon is this close to Earth, distinctive lunar surface features such as impact craters can be seen with the naked eye.
"I've been telling people to go out at night on either Sunday or Monday night to see the supermoon," Petro said in a statement from NASA. "The difference in distance from one night to the next will be very subtle, so if it's cloudy on Sunday, go out on Monday. Any time after sunset should be fine. Since the moon is full, it'll rise at nearly the same time as sunset, so I'd suggest that you head outside after sunset, or once it’s dark and the moon is a bit higher in the sky. You don’t have to stay up all night to see it, unless you really want to!”
