Over millions of years, Uranus’s inner moons may have collided and spread out into rings. As the material in the rings diffused, they moved farther away from the planet. Eventually, that material can start to accumulate, recycling itself back into a moon.

Jupiter, Mercury, Neptune, Saturn, Uranus and Venus will be visible in the early morning skies over America from Sunday, Aug. 17, to Wednesday, Aug. 20. FOX 5's Liv Johnson reports.

Mark your calendar so you can catch Mercury, Venus, Jupiter, Saturn, Neptune and Uranus in the sky at the same time.

A new study on Uranus has found it is hotter than we thought, prompting scientists to suggest we should return to the ice giant. While Mars, Jupiter, and Saturn are regularly visited by human spacecraft,
