More about the news:

  • This was the second occurance of such a Super Pink Moon this year which lit up the night skies.
  • This Super Moon was also one of the brightest and the biggest full moons of 2020. Due to this it was widely publicised as ‘Pink Supermoon’.
  • Current Super Pink Moon was the closest the Moon has ever got to the Earth in 2020
    • The average distance between the Moon and the Earth is 3,84,400 km whereas this Super Full Moon was only 35,035 km away from the Earth.

About the supermoon

  • When does a supermoon occur?
    • This phenomena occurs  when the Moon is "full" and reaches perigee 
      • Perigee:The point in the orbit of the Moon at which it is nearest to the Earth. 
      • Apogee:The point in the orbit of the Moon at which it is farthest to the Earth.
    • In other words when a full Moon is nearest to the Earth, a supermoon occurs.
    • Supermoons only happen a few times a year (at most) because the moon's orbit changes orientation while the Earth orbits the sun — that's why you don't see a supermoon every month.
  • Why are they called Supermoon?
    • A supermoon happens when the full moon coincides with the moon's closest approach to Earth in its orbit.
    • They are called supermoons because compared to an average full Moon, supermoons appear around 30 percent brighter and 14 percent larger.

  • Rationale behind calling it pink
    • The Super Pink Moon isn't pink in colour actually
    • Traditionally, the full moon in the month of April is named after a certain pink flower 'Wild Ground Phlox’, which blossoms during this month.This flower is native to eastern North America.
    • Therefore pink refers to the color of the flower not the color of the moon.

 

Other different types of moon

Blood Moon

  • A "blood moon" happens when Earth's moon is in a total lunar eclipse. 
  • While it has no special astronomical significance, the view in the sky is striking as the usually whiteish moon becomes red or ruddy-brown.

Blue Moon

  • Term Blue Moon has been applied to the second full moon within a single calendar month
  • As there are roughly 29.5 days between full moons, making it unusual for two full moons to fit into a 30- or 31-day-long month. 
  • This means that February will never have a Blue Moon.
