What is this Super blue blood moon?
Super moons occur when the full moon coincides with the Moon’s closest orbit point (perigee) to the planet. During a super moon, the Moon appears upto 14 per cent larger and 30 per cent brighter, according to NASA. Remember most celestial bodies in our solar system have an elliptical orbit. These include the orbit of the Earth around the Sun, as well as the orbit of the Moon. The farthest distance between the moon and the Earth is termed ‘apogee’, while the perigee is the nearest point between planet Earth and its satellite.
The reason this January 31 event is a Super blue blood moon is because this will also be a total lunar eclipse, when the satellite has reddish tinge to it. It is also the second total lunar eclipse in the month of January 2018, and according to NASA, a second total lunar eclipse during a month is called ‘blue moon’. Thus the Super moon has become a “super blue blood moon.”

What is a total lunar eclipse?
An eclipse is when three celestial bodies which are Sun, Moon and Earth are aligned in one path. A total lunar eclipse is where the moon is blocked entirely by the Earth’s shadow, as the Earth comes between the Sun and the Moon. Totally eclipsed moons are called blood moons because they tend to take on a reddish hue due to how Earth’s atmosphere scatters blue light but allows red wavelengths to pass through. This year January 1, 2018, also saw a Supermoon rise.
What is a blue moon?
When a full moon occurs twice in a month, the second full moon is called a blue moon. This also led to the term ‘Once in a blue moon’, as it is relatively rare to witness.
