“The supermoons are a great opportunity for people to start looking at the
Moon, not just that once but every chance they have!” says Noah Petro, a
research scientist from NASA’s Goddard Space Flight Center. (Quoted from https://science.nasa.gov)
A supermoon is a full Moon
which
is in the closest point of the orbit of the Moon around the Earth. The orbit of the Moon around the Earth is elliptical. The farthest point is
called apogee and the closest point is called perigee. The apogee is 30,000
miles or 50,000 km farther than the perigee.
Full moons that happen near the perigee look 14% bigger and 30% brighter
than full moons that happen near the apogee. That means a supermoon is the
biggest and brightest moon you are able to see with your own bare eyes!
The first supermoon of the supermoon trilogy already happened on 3rd December 2017. The
second one happened
on 1st January 2018. The third one which is
the most special supermoon will happen on 31st January 2018.
You will not want to miss the January 31st supermoon, which is the last
supermoon in the supermoon trilogy! The last of the supermoon trilogy will be
the most special supermoon in the trilogy because of these following reasons:
1. The third supermoon will happen with a total lunar eclipse.
The total lunar eclipse will be able to be seen from western North America
across the pacific to Eastern Asia. A total lunar eclipse happens when the Sun,
the Earth, and the Moon are in exactly one line. The Earth blocks the light of
the Sun which is reflected by the Moon.
Because of that, the Moon lose its light and looks dark. A total lunar eclipse only happens
once in about two years.
The third supermoon will be the second full Moon of the
month The second full of the month is called
a Blue Moon. For addition, a Blue Moon is very
rare because it only happens every two and a half years.
A supermoon which is also a Blue Moon that happens with a total lunar eclipse
will happen again in more than two years. Missing the chance to see the most
special supermoon is a real waste. So, mark your calendar on 31st January
2018 and make sure that you will not miss the chance to see that most special supermoon of the
Supermoon
Trilogy with
your own eyes!
