An official said that Saturn would be exactly opposite the Sun, while the Earth would orbit between the two and will be approximately 1,346 million kilometres from the planet.

“After sunset, Saturn should be visible to the naked eye in the Southeast all night,” an official said. “If you look through a telescope with a diameter of at least 4 inches or magnification over 50 times, you can see Saturn’s A and B rings.”

The official added that Jupiter should be visible near Saturn as well.

“The institute will set up a telescope at its observatories in Nakhon Ratchasima, Chachoengsao and Songkhla, as well as at Chiang Mai’s Sirindhorn Astronomical Park. People can catch sight of Saturn for free between 6pm and 10pm.
