An eclipse is when the Moon passes in front of the Sun and it casts a shadow across Earth. Another name is Occultation. The reason behind this is that the distance between the sun and the earth is about 400 times the moon’s distance from the sun. The sun’s diameter is approximately 400 times larger than the moon’s which means that the sun and the moon seems to be similar size when viewed from earth. So, when the moon passes in front of the sun the light is blocked to reach the earth. Some more fun facts about solar eclipse are-

  • There are three different types of solar eclipse. Partial, Annular and Total eclipse.
  • There are three types of Lunar eclipse. Partial, Full, and Prenumbral.
  • The Danjon Scale is a scale used to describe the darkness of a total lunar eclipse.
  • There are 2-5 solar eclipse each year.
  • The moon completely obscuring the sun and leaving only faint solar corona is known as total solar eclipse.
  • Total solar eclipses are rare. It happens only once in every 18 months.
  • Hybrid eclipse are between a total and annular eclipse depending on the place of earth we are watching it. These are comparatively rare.
  • The moon moves across the sun in approximately 2250km per hour.
  • Only a partial eclipse can be viewed from the North or South Pole.
  • A total solar eclipse can last 7 minutes and 30 seconds maximum.
  • Almost identical eclipse can be seen which is known as Saros Cycle and it occurs after 18 years and 11days.
  • Its total coincidence that we can see total eclipse. No other planet has total eclipses and at some point in the future it won’t occur in earth as well.
  • Helium is named after Greek God Helios because the first evidence was not found on earth but on the sun during a solar eclipse in 1868.
  • Solar eclipses are more dangerous to view directly because the sun dialects from the dark eclipse which allows remaining sunshine to cause more damage.
  • If you were on the moon during a total eclipse, you would see every sunset and sunrise on earth as a red ring around the globe.
  • Some people in India still believe that one should wash eyes out with the first urine of the day on a solar eclipse day to avoid pain.
  • A total solar eclipse in 1925 had a path of totality that just grazed Manhattan.
  • All eclipse calculations are by Fred Espenak and he is responsible for all accuracy.
  • Some Native Americans don’t step outside during eclipse and fast and pray.
  • The first believed recording of a solar eclipse was over 5000 years ago in 3340BC.
  • A solar eclipse always occurs two weeks before or after a Lunar eclipse.
  • Lunar eclipses only occur during a full moon.
  • Solar eclipses only occur during a new moon.
  • Eclipses often occur in threes which means alternating lunar, solar and then lunar again.
  • The maximum time for a lunar eclipse is 3 hours and 40 minutes.
  • Lunar eclipses can occur upto three times a year.
  • Lunar eclipses are visible over an entire hemisphere while solar eclipses are visible in a narrow path a maximum of 167 miles wide.
  • The eclipse shadow moves at 2000 mph at the Earth’s Poles.
  • The eclipse shadow moves at 1000 mph at the Earth’s equator.
