Asteroids Earth NASA
NASAs Eyes on Asteroids brings this data to any smartphone tablet or computer with an internet connection no download required. NASA has warned that at least five asteroids will hurtle past Earth this month - and one is the size of Big Ben.

. A mission called GRACE Gravity Recovery and Climate Experiment has a satellite that orbits Earth and maps the gravity across the surface. Thousands of asteroids and dozens of comets are discovered every single year some of which called near-Earth objects NEOs follow orbits that pass through the inner solar system. NASA will launch four Earth science missions in 2022 to provide scientists with more information about fundamental climate systems.
In the first NASA is directed to lead a new effort to enhance the nations capabilities for detecting tracking and characterizing near-Earth asteroids to reduce current levels of uncertainty. NASA will launch four Earth science missions in 2022 to provide scientists with more information about fundamental climate systems. KTALKMSS A NASA engineer with ties to Shreveport is at the center of a mission to protect future generations from the threat of asteroids slamming into Earth.
The extraterrestrial objects were. Specifically all asteroids with an Earth Minimum Orbit Intersection Distance MOID of 005 au or less and an absolute magnitude H of 220 or less are considered PHAs. NASA To Launch 4 Earth Science Missions in 2022 The new system improves NASAs capabilities to assess the impact risk of asteroids that can come close to our planet.
In other words asteroids that cant get any closer to the Earth ie MOID than 005 au roughly 7480000 km or 4650000 mi or are smaller than about 140 m 500 ft in. The differences in gravity across Earth are called gravity anomalies. But Earth has mountains oceans valleys and other features.
If the Earth were smooth and perfect gravity would be the same everywhere.
