Roll out the cosmic welcome mat for our solar system’s newest resident: a never-before-seen moon orbiting Uranus.

A team of astronomers announced Tuesday that a new satellite measuring roughly 90 football fields across was discovered around the seventh planet from the sun. The moon, which was first seen by NASA’s James Webb Space Telescope on Feb. 2, joins a busy neighborhood of 28 other known moons around Uranus.

The Webb telescope’s observations of Uranus are giving scientists better insight into one of the more mysterious planets in our solar system.

“No other planet has as many small inner moons as Uranus,” Matthew Tiscareno, a member of the research team and a senior research scientist at the SETI Institute in California, said in a statement.

Tiscareno said the “complex inter-relationships” between Uranus’ moons and its faint rings suggest the planet’s evolutionary history may have been a chaotic one.

“Moreover, the new moon is smaller and much fainter than the smallest of the previously known inner moons, making it likely that even more complexity remains to be discovered,” he said in the statement.

The newfound satellite is about 35,000 miles from the center of the planet, with a near circular orbit, according to the researchers.

It’s only about 6 miles across — a distance that can be walked in about two hours at a brisk pace — but follow-up observations are needed to confirm the moon’s size and other characteristics.

The discovery has also not yet been peer-reviewed.

Uranus has five large, outer moons named Miranda, Ariel, Umbriel, Titania and Oberon. The newly discovered moon is inside the orbits of the five larger moons, the researchers said.

All of Uranus’ moons are named after characters from the works of Shakespeare and Alexander Pope, according to NASA. The new moon does not yet have a name, though any designation will eventually need to be approved by the International Astronomical Union, which oversees the official naming process for astronomical objects.

“It’s a small moon but a significant discovery, which is something that even NASA’s Voyager 2 spacecraft didn’t see during its flyby nearly 40 years ago,” Maryame El Moutamid, a lead scientist in the Southwest Research Institute’s Solar System Science and Exploration Division, said in a statement.

In 1986, the Voyager 2 probe became the first human-made object to fly past Uranus, giving humanity its first close-up views of the distant planet. The historic encounter yielded more than 7,000 photographs of Uranus and helped scientists discover two new rings and 11 new moons around the planet.

The newest moon’s tiny size likely made it too small for Voyager 2’s cameras to see, but the Webb telescope’s high-resolution instruments may shed more light on the planet and its system.

“Looking forward, the discovery of this moon underscores how modern astronomy continues to build upon the legacy of missions like Voyager 2,” El Moutamid said in the statement. “Now, nearly four decades later, the James Webb Space Telescope is pushing that frontier even farther.”

No doubt governed by a little prince.

So they're talking about how long it would take to walk straight through the object, assuming there was a tunnel through it. The circumference of a 6 mile diameter sphere is 19 miles, so it'd take roughly 16 and a half hours to walk that far at that speed.

Assuming this is a comet-like object in terms of physical makeup, I get an orbital velocity of 1.8 meters per second at ground level. The walking speed assumed here is 1.3 meters per second, which is conveniently close. So what you'd want to do is find a sturdy vertical surface to brace yourself on (which might be hard to find on an object like this) and push off horizontally across the terrain to put yourself in as low an orbit as possible. You'll want it to be a bit more parabolic than circular to avoid hitting any obstructions, but you're moving a bit faster this way so it should work about about the same.
