Welcome to NASA Earth Observations, where you can browse and download imagery of satellite data from NASAs Earth Observing System. Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats.
Close Approaches. As they orbit the Sun, Near-Earth Objects occasionally approach close to Earth. CNEOS calculates the motion of all NEOs forwards to 2200 A.D. and backwards to 1900 A.D.,and determines the times and distances of the Earth close approaches. The results are tabulated here.

11 paź 2024 · Every month dozens of NEAs come within 0.05 au of Earth. The following table presents the list of these forthcoming and recent close approaches, with details concerning the encounter circumstances.
8 lut 2021 · GetCapabilities provides information on what is available with a WMS service and GetMap provides the image map along with the image-specific metadata. NEO’s Capabilities Document is located on the WMS information page. How to use the NEO WMS service. There are several ways to connect to NEO’s WMS server with different software.
The Near-Earth Object (NEO) Observations Program is a key element of NASA’s Planetary Defense Program, funding efforts to search for undiscovered NEOs using observatories around the world, calculate and refine NEO orbits, determine NEO physical properties and composition, and study NEO deflection and mitigation technologies.
