Asteroid Apophis has One in 100,000 chance of hitting Earth

The huge nearly 400-meter wide asteroid Apophis is still on a list of hazardous near-Earth objects (NEOs), regarded as a potential threat to our planet. However, new calculations made by NASA’s Jet Propulsion Laboratory (JPL) scientist, show that Apophis’ odds of Earth impact are lower than previously estimated.

“We cannot yet exclude the possibility that it could impact our planet,

Large Asteroid to Safely Pass Earth on Sept. 1

Asteroid Florence, a large near-Earth asteroid, will pass safely by Earth on Sept. 1, 2017, at a distance of about 4.4 million miles, (7.0 million kilometers, or about 18 Earth-Moon distances). Florence is among the largest near-Earth asteroids that are several miles in size; measurements from NASA’s Spitzer Space Telescope and NEOWISE mission indicate it’s about 2.7 miles (4.4 kilometers) in size.

Asteroid to shave past Earth on Oct 12: ESA

A house-sized asteroid will shave past our planet on October 12, far inside the Moon’s orbit but without posing any threat, astronomers said Thursday.

The space rock will zoom by harmlessly at a distance of about 44,000 kilometres (27,300 miles) — an eighth of the distance from the Earth to the Moon,

Asteroid Flyby Will Benefit NASA Detection and Tracking Network

NASA scientists are excited about the upcoming close flyby of a small asteroid and plan to use its upcoming October close approach to Earth as an opportunity not only for science, but to test NASA’s network of observatories and scientists who work with planetary defense.

The target of all this attention is asteroid 2012 TC4 —

Close shave from an undetected asteroid

Astronomers discovered a small asteroid – now designated as asteroid 2017 OO1 – on July 23. That was 3 days after it passed 1/3 the moon’s distance from Earth.

A space rock now designated as asteroid 2017 OO1 was detected on July 23, 2017 from the ATLAS-MLO telescope at Mauna Loa,

Large, Distant Comets More Common Than Previously Thought

Comets that take more than 200 years to make one revolution around the Sun are notoriously difficult to study. Because they spend most of their time far from our area of the solar system, many “long-period comets” will never approach the Sun in a person’s lifetime. In fact, those that travel inward from the Oort Cloud –

Ancient, massive asteroid impact could explain Martian geological mysteries

The origin and nature of Mars is mysterious. It has geologically distinct hemispheres, with smooth lowlands in the north and cratered, high-elevation terrain in the south. The red planet also has two small oddly-shaped oblong moons and a composition that sets it apart from that of the Earth.

New research by University of Colorado Boulder professor Stephen Mojzsis outlines a likely cause for these mysterious features of Mars: a colossal impact with a large asteroid early in the planet’s history.

LISA Pathfinder hunts asteroids

This tiny, perfect mission has not only proven the technology needed to detect gravity waves in the future full LISA mission, it has also gone looking for asteroids!

Near-Earth objects (NEOs) are asteroids that come close to Earth that could potentially impact our planet, causing damage.

While ground-based telescopes are used to search for and follow up these objects,

ESO and ESA Reach Agreement to Site Test-Bed Telescope at La Silla

In August 2015, ESO and the European Space Agency (ESA) signed a cooperation agreement setting the terms and conditions for mutual cooperation and the exchange of scientific research information between the two organisations. The first project to be implemented under this cooperation agreement is the deployment of a Test-Bed Telescope at ESO’s La Silla Observatory in northern Chile.

NASA’s Asteroid-Hunting Spacecraft a Discovery Machine

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission has released its third year of survey data, with the spacecraft discovering 97 previously unknown celestial objects in the last year. Of those, 28 were near-Earth objects, 64 were main belt asteroids and five were comets.

The spacecraft has now characterized a total of 693 near-Earth objects since the mission was re-started in December 2013.
