What is a penumbral lunar eclipse?
There will be several penumbral lunar eclipses in 2020.
That’s because it occurs when the moon is in the Earth’s outer (penumbral) shadow and can be hard to see unless you have a seasoned eye for these things.
What is a total solar eclipse.
A total solar eclipse is when the moon is between the Earth and the sun and therefore the moon casts a shadow on the Earth, according to space.com.
On average, a total solar eclipse occurs about once every 18 months.
According to NASA, the moniker was coined by an astrologer in 1979 and is often used to describe a full moon happening near or at the time when the moon is at its closest point in its orbit around Earth.
What is a blue moon.
A seasonal blue moon is the third full moon in a season of four full moons.
A blue moon can also refer to the second full moon in a calendar month.
