Uranus

The planet Uranus and its five biggest moons may not be the dead sterile worlds that scientists have long thought.

Taking advantage of a gravitational convergence of four planets that occurs only once every 176 years, the spacecraft soared past Jupiter, Saturn, Uranus and Neptune.

On the other hand, Uranus is oriented a whopping 97.8 degrees from vertical, causing one of its poles to point directly at the sun at times.

The parade will start June 3, when Mercury, Mars, Jupiter, Saturn, Uranus and Neptune will be aligned, according to Star Walk Astronomical News, a planetarium phone app.

The team also measured sulfur dioxide, water vapor, carbon dioxide, and carbon monoxide -- and found WASP-107 b has more heavy elements than Uranus and Neptune.
