The Millennium Super moon has been the topic since
last night! So did you grab this chance? Or you’ve missed it?
As
a crazy fan of astronomy enthusiasts, I also missed to see the super moon
yesterday! So sad! Don’t worry, now we BMKP make a short summary connected with
the super moon.
The
super moon is a made-up term,” said James Lattis, an
astronomer at the University of Wisconsin-Madison. “It’s not an astronomical
term, there’s no technical definition of it.”
Super
moon was actually coined by an astrologer in the 1970s, not by a scientist. The
term has come to loosely mean a full moon that is at perigee, or when the moon
is at its closest position to Earth along its orbit.
Compared
to an average full moon, this super moon will be approximately 7 percent larger
and 15 percent brighter. But most people won’t be able to tell the difference
between it and a regular moon.
“There’s
no fireworks show, no blinking sign that says, ‘Hey, this is the super moon!’”
said Noah Petro,
a deputy project scientist for the Lunar Reconnaissance Orbiter mission.
Instead,
the super moon really shines when it is compared with the full moon at apogee,
or its farthest position from Earth. If you place images of the two side by side, you can see
the difference more easily, Dr. Petro said. The super moon is 14 percent larger
than the apogee full moon and 30 percent brighter.
On
average, the moon is about 238,900 miles away from Earth. But Sunday and
Monday’s super moon will be approximately 221,524 miles away.
Astronomers
measure the distance of the moon from Earth by shooting lasers to the surface
of the moon, which then bounce off mirrors called retro reflectors, which were
left behind by the Apollo missions and two Soviet Landers.
Even
though most people will not notice anything special about this super moon, Dr.
Petro said it will still be a good excuse to start gazing at the night sky more
regularly.
If
you are busy in daily life and confused to where to find the super moon, you
could call BMKP to customize your route. Never miss the super big moon next
time!
