(CNN) – An international team of astronauts has discovered new measurements of how long a day is on Uranus.

The team used the Hubble Space Telescope to track the planet’s rotation period.

By using a new technique, they found that Uranus completes a full rotation in 17 hours, 14 minutes and 52 seconds.

That’s 28 seconds longer than the previous estimate in 1986.
