The good news: NASA has discovered the 10,000th near-Earth object (NEO).
The bad news: At least 100,000 are still out there.

NEOs are asteroids and comets that approach Earth, coming within 28 million miles (45 million kilometers) of our planet during their orbit around the sun. The vast majority of these chunks of space rock and ice are harmless - they just fly right by, minding their own business, in well-defined, well-known orbits.
NEOs also come in a range of sizes, from the pipsqueak few-footers to the rather terrifying whopper, 1036 Ganymed, that measures 25 miles (41 kilometers) across.
And now NASA has discovered the 10,000th NEO - a 1,000 feet (300 meters) wide asteroid affectionately named 2013 MZ5.
"Finding 10,000 near-Earth objects is a significant milestone," said Lindley Johnson, program executive for NASA's Near-Earth Object Observations (NEOO) Program at NASA Headquarters. "But there are at least 10 times that many more to be found before we can be assured we will have found any and all that could impact and do significant harm to the citizens of Earth."
