Where is JUICE (Jupiter Icy Moons Explorer) now?
Today JUICE (Jupiter Icy Moons Explorer) is 0.093 au (13.91 million km) from Earth and 0.921 au from the Sun. Its radio signals take 46 s to reach us. It is moving away from Earth at 11.4 km/s.
In our sky it is in Leo (right ascension 11h 10m 30s, declination +05° 18′ 19″), but far too faint to see.
Where it is in the Solar System
Seen from above the plane of Earth’s orbit, with the Sun in the middle: the planets’ orbits, the spacecraft today and its path a year back and a year ahead (where JPL’s trajectory covers it).
Mission
Will study Jupiter and its ocean-bearing moons Ganymede, Callisto and Europa as planetary objects and possible habitats.

How to use this page
The page shows where the spacecraft is now, its path through the solar system, its key facts and its main milestones, from NASA JPL’s data.
Frequently asked questions
How is the position worked out?
From NASA JPL Horizons, which publishes the trajectories of spacecraft. The page is refreshed daily.
Can I see it in the sky?
No. Deep space probes are far too small and far away to see, even with a large telescope.
How do we talk to it?
Through NASA’s Deep Space Network, large radio dishes in California, Spain and Australia.
