Planets
Our interactive sky map allows you to observe the position of the planets in the solar system in the sky today.
Find in real time Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune according to your location.
Sky map
We reproduce the sky with the 8 planets of the solar system, the Moon, the Sun and the Milky Way.
We accurately calculate and display their apparent positions in the sky in real time, taking into account :
- local sidereal time of the selected observation location,
- celestial coordinates of the stars, proper motion, precession, nutation and aberration of light,
- date and time.
The celestial vault is delimited to reveal which celestial objects are currently visible in the sky.
The compass tells you which direction you are looking, you can select another city to observe the sky from its position.
Use the buttons to travel through time and observe how celestial objects move in the sky as the earth rotates.
