On Aug. 14, 2021, a small near-Earth asteroid (NEA) designated 2021 PJ1 passed our planet at a distance of over 1 million miles (about 1.7 million kilometers).

Near Earth Asteroids, or NEAs, pass by our home planet all the time. But an SUV-size asteroid set the record this past weekend for coming closer to Earth than any other known NEA: It passed 1,830 miles (2,950 kilometers) above the southern Indian Ocean on Sunday, Aug. 16 at 12:08 a.m. EDT (Saturday, Aug. 15 at 9:08 p.m. PDT).

A new multiagency report outlines how the U.S. could become better prepared for near-Earth objects -- asteroids and comets whose orbits come within 30 million miles of Earth -- otherwise known as NEOs.

An international team of astronomers led by NASA scientists successfully completed the first global exercise using a real asteroid to test global response capabilities.

Puzzling Asteroid Observations Explained

An international team composed of researchers from Finland, France, the United States and the Czech Republic originally set out to construct a state-of-the-art model of the NEO population that is needed for planning future asteroid surveys and spacecraft missions.

NASA has formalized its ongoing program for detecting and tracking near-Earth objects (NEOs) as the Planetary Defense Coordination Office (PDCO).

A small asteroid, designated 2014 RC, will safely pass very close to the Earth on Sunday, 7 September 2014.

In the last decades Near-Earth Objects (NEOs) have become very important targets to study, since they can give us clues to the formation, evolution and composition of the Solar System.

A newfound asteroid will safely pass Earth on June 8 from a distance of about 777,000 miles (1.25 million kilometers), more than three times farther away than our moon.

For nearly as long as astronomers have been able to observe asteroids, a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites -- the remnants of asteroids that have crashed to Earth?

A team of astronomers from the National Astronomical Observatory of Japan and the University of Hyogo used the Subaru Prime Focus Camera (Suprime-Cam) mounted on the Subaru Telescope to observe faint asteroids with highly inclined orbits.

At a public event today at New York's American Museum of Natural History, the Association of Space Explorers (ASE), a professional society of astronauts and cosmonauts, issued a challenge to the global community to take the next vital steps to confront the threat from dangerous asteroids.

An Asteroid and the Orion Nebula

This image shows the potentially hazardous near-Earth object 1998 KN3 (top-upper-left yellow-green dot) as it zips past a cloud of dense gas and dust near the Orion nebula.

On May 22nd the European Space Agency (ESA) opened its new Near-Earth Object (NEO) Coordination Centre so it can contribute to the global effort in discovering asteroids and other hazardous natural objects that may strike Earth.

On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. And while QE2 is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of interest to those who dabble in radar astronomy and have a 230-foot (70-meter) -- or larger -- radar telescope at their disposal.

The striking coincidences of the asteroid 2012 DA14 flying close to the Earth, and a large meteor crash in Russia's Chelyabinsk region on 15 February, showed again the need for coordinated international efforts to predict, and if necessary, mitigate such threats posed by near-Earth objects in the future.

"This article describes a citizen-science project conducted by the Spanish Virtual Observatory (SVO) to improve the orbits of near-Earth asteroids (NEAs) using data from astronomical archives. The list of NEAs maintained at the Minor Planet Center (MPC) is checked daily to identify new objects or changes in the orbital parameters of already catalogued objects. Using NEODyS we compute the position and magnitude of these objects at the observing epochs of the 938 046 images comprising the Eigth Data Release of the Sloan Digitised Sky Survey (SDSS). If the object lies within the image boundaries and the magnitude is brighter than the limiting magnitude, then the associated image is visually inspected by the project's collaborators (the citizens) to confirm or discard the presence of the NEA. If confirmed, accurate coordinates and, sometimes, magnitudes are submitted to the MPC." More

NASA Television will provide commentary starting at 11 a.m. PST (2 p.m. EST) on Friday, Feb. 15, during the close, but safe, flyby of a small near-Earth asteroid named 2012 DA14. NASA places a high priority on tracking asteroids and protecting our home planet from them. This flyby will provide a unique opportunity for researchers to study a near-Earth object up close.

Close Earth Flyby By Asteroid 2012 DA14

A little-known asteroid will skim past Earth on 15 February, passing just 28 000 km from our planet. The 50 m-diameter chunk of space rock was discovered in last year by ESA-sponsored amateur astronomers in Spain.

Herschel Intercepts Asteroid Apophis

ESA's Herschel space observatory made new observations of asteroid Apophis as it approached Earth this weekend. The data shows the asteroid to be bigger than first estimated, and less reflective.
