Whether you’re a late sleeper or an early riser, be sure to look up to the sky on Friday night, June 24, and Saturday, June 25. The planets of the solar system are aligned. A rare phenomenon that will not occur again until 2124.

From the second part of the night, observers will be able to observe, with the naked eye, five planets one after the other: “They do exactly like the sun. If we look at the eastern horizon, we see them gradually rise in the sky, “explains our colleagues of Franceinfo Emmanuel Marcq, teacher-researcher in planetology at the University of Versailles-Saint-Quentin.

Saturn will open the ball “around one o’clock in the morning”, then Jupiter, Mars, the Moon, then Venus and Mercury, before the sunrise between 5 and 6 am. As for Neptune and Uranus, a telescope is still necessary.
