Tiny New Moon Discovered around Neptune

The Hubble Space Telescope has revealed a small, never-before-seen moon around Neptune, boosting the giant blue planet's total satellite count to 14 satellites, new photos reveal.

 

The newfound Neptune moon ? called S/2004 N 1 ? was discovered July 1 during a fresh analysis of older Hubble Space Telescope images, scientists said. The newly discovered satellite is Neptune's smallest known moon and is just 12 miles (19 kilometers) wide.

 

Hubble telescope scientists announced the new Neptune moon's discovery today (July 15). The small satellite wasn't easy to find.

 

"The moons and arcs [segments of rings around the planet] orbit very quickly, so we had to devise a way to follow their motion in order to bring out the details of the system," SETI Institute scientist Mark Showalter, the moon's discoverer, said in a statement. "It's the same reason a sports photographer tracks a running athlete ? the athlete stays in focus, but the background blurs."

Is that big enough to classify as a moon?

That's what I thought, more on the lines of space junk than moon. Sounds more like a mini asteroid locked in orbit.

I'm pretty sure the rule is simply if the satellite is orbiting the thing it's considered a moon. But yeah that seems super small.

If they're going to call that a moon, they need to put Pluto back as a planet.

Or just write it as a Moon for decades in the History Books and then change their damn minds and say it's a Dwarf Moon just to **** with people. Cosmologists are the worst kind of trolls.

There is no size requirements for moons. If it orbits the planet, be it naturally formed, or a captured asteroid, it's still a moon.
