The month of April is set to bring a moment of joy for the sky-watchers as they will get a pre-dawn treat when four planets gather low in the eastern sky.

While not a perfect "string of pearls," the lineup of Saturn, Mars, Mercury and Neptune is dubbed as a 'mini planet parade'. They will be visible just before sunrise.

According to National Geographic, Saturn, Mars and Mercury will appear close enough to share the same field of view when looked through binoculars. But with a telescope, stargazers can also observe Neptune as it comes into view above them.

This parade is not a one-day show. It started around April 12, and it is expected to become dramatic from April 16 to 21. It's the period when the planets appear within about two to three degrees of each other.

Around April 20, expect to see three planets with the naked eye - Mercury, Mars and Saturn - forming a short line. Neptune requires binoculars or a telescope.

India is one of the better places in the Northern Hemisphere to catch it. The four planets sit low in the east before sunrise, but from much of India, the geometry is more favourable than at higher northern latitudes.
