In 1986, NASA’s Voyager 2 conducted a flyby of Uranus, providing key insights into the planet’s magnetic field and plasma environment.
Recent studies suggest that the data collected was misleading due to unusual solar wind conditions at the time.
This new understanding alters previous conclusions about Uranus’ magnetosphere and plasma characteristics.

Voyager 2 is the only spacecraft to have visited Uranus, conducting a flyby in 1986.

Uranus has a unique tilt, rotating on its side at an angle of about 98 degrees, which causes extreme seasons.
It is an ice giant, primarily composed of hydrogen, helium, water, and methane.
