When Sun, Earth, and Moon come in a line, the Earth’s shadow prevents the sunlight to fall on the Moon and results in Lunar eclipse. The complete Lunar eclipse in 2018 is Chandra Grahan 2018. This includes the second full Moon of the month which is known as Blue Moon. Moon comes close to Earth at this time. This is called Super Moon. Because of this, the Lunar eclipse 2018 is known as Super Blue Blood Moon.
