September 16, August 16, July 15, Roundness is key, experts said, because it indicates an object has enough self-gravity to pull itself into a spherical shape. Yet Earth's moon wouldn't qualify because the two bodies' common center of gravity lies below the surface of the Earth.

But Pluto has gravity on its side. By the physics of our proposed definition, Pluto makes it by a long shot. Ekers said the draft definition, two years in the making, was an attempt to reach a cosmic consensus and end decades of quarreling. Neil deGrasse Tyson, director of the Hayden Planetarium at New York's American Museum of Natural History - miscast as a "Pluto-hater," he contends, merely because Pluto was excluded from a solar system exhibit - said the new guidelines would clear up the fuzzier aspects of the Milky Way.

Full Moon Guide: October - November A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought. This year, the minimum extent of Arctic sea ice dropped to 1. The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes.

Researchers will use Webb to observe 17 actively forming planetary systems. Scientists found evidence that an area on Mars called Arabia Terra had thousands of "super eruptions" over a million-year period. Perseverance successfully collected its first pair of rock samples, and scientists already are gaining new insights into the region. Data received late Sept. The rover will abrade a rock this week, allowing scientists and engineers to decide whether that target would withstand its powerful drill.

Drought is a complicated problem that requires lots of data.
