During a Solar Eclipse the sun would disappear completely behind the moon for a few minutes. Partial lunar eclipse generally occurs twice a year however the solar eclipse occurs approx. at a gap of 18 months. The location of the solar eclipse is different every time. The eclipse occurs at the same spot only once every 370 years.

Lunar Eclipse is visible on the entire night side of the earth whereas Solar eclipse is only visible in very small portions. Watching a lunar eclipse with the naked eye is absolutely safe whereas watching the Solar Eclipse with a naked eye is very dangerous. The duration of the Lunar Eclipse may last for almost an hour whereas the Solar Eclipse can be six to seven minutes at best.
