Stargazers are in for a treat on March 29 when Venus, Mars, Jupiter and Mercury line up in the sky in a rare event that happens about every 32 years.
"All these planets will line up along an east-west belt in the sky," Dr N Rathnasree, Director, Nehru Planetarium, said in New Delhi.
Though these planets will be visible to the naked eye, use of telescope will allow viewers to view moons of Jupiter, rings of Saturn and phases of Mercury, she said.
The simplest way to locate the planets is to look for Venus in the western skies immediately after sunset.
A little above Venus will be Mars, in the same west-east line will be Saturn, and further in the line towards the eastern horizon will be Jupiter. Mercury will be seen a little below Venus, she said.
While Venus, Mars, Saturn and Jupiter are already visible in the evening sky, Mercury will join them at the end of March, she said. They will be best visible on March 29 as Mercury and Venus will be then at their maximum angular distance from the sun.
