CT residents will have their eyes peeled to the sky Sunday night as the "supermoon" makes its only appearance in 2017. Perigee is the point in the moon's orbit at which the moon is closest to the Earth. The result is that the full "super" moon appears slightly larger and slightly brighter to us in the sky.
Rare natural phenomenon in the night of 4 December will be able to observe scientists and Amateur astronomers, the Moon will approach Earth at the closest distance for the last 6 years. That means during each month the moon is sometimes passing closer to the earth than others.
The distance between the moon and Earth constantly changes.
The moon will be visible to see on Sunday after 5 p.m. when it begins to rise, however, it won't officially be a Supermoon until it is at its closest point to Earth, which will be at approximately 4 a.m. on Monday.
"It is said that the moon appears larger because we compare it with terrestrial objects such as trees or buildings".
The January 31 supermoon will also be the second full Moon of the month. This is also why both times are the best for watching the supermoon.
An image of the moon taken by NASA's Lunar Reconnaissance Orbiter is shown in two halves to illustrate the difference between the apparent size of a supermoon (left) and a "micromoon" (right). That'll be a super moon, even by Neil deGrasse Tyson's standards. "Then slide your finger up or down to darken or lighten the exposure". "Still, it's a great excuse to just go out and look at the sky", says Nichols. "It's a fun way to get involved in science".
