Five hundred-metre-wide asteroid 2017 CS passes just 1.9 million miles, or 7.9 lunar distances, from Earth on the afternoon of Monday 29 May 2017. For a few nights around this date, Northern Hemisphere observers with 6-inch and larger ‘scopes can see the asteroid gallop through the constellations of Canes Venatici, Boötes and Hercules at up to 14 degrees/day.
A peanut-shaped asteroid almost a mile long known as 2014 JO25 passes within 5 lunar distances of Earth on 19 April — the closest any known space rock of this size has approached our planet since September 2004. We show you how to find this fast-moving potentially hazardous asteroid in small telescopes during the UK night of 19-20 April.
Las Cumbres Observatory have partnered with Asteroid Day 2016 and Universe Awareness to create a website which allows you to use a global network of robotic telescopes to take pictures of two asteroids — 2002 KL6 and 2010 NY65 — currently passing close to Earth. On the website you can join the international campaign to study and raise awareness about asteroids.
A small asteroid designated 2016 HO3 has been discovered in an orbit around the Sun that keeps it as a constant companion of Earth, and it will remain so for centuries to come. It is too distant to be considered a true satellite of our planet, but it is the best and most stable example to date of a near-Earth companion, or “quasi-satellite.”
On 14 March, the ExoMars spacecraft and Schiaparelli lander were lofted into orbit by a Proton rocket, starting a seven-month journey to the Red Planet. For the ExoMars launch, ESA’s near-Earth object (NEO) coordination centre in Italy organised a successful international campaign for ground-based optical observations of the departing spacecraft.
Discovered by the Catalina Sky Survey on 6 October 2013 a week before its last close flyby of Earth, 30-metre-wide asteroid 2013 TX68 was initially thought to pass by Earth again on 5 March 2016. Additional observations of the body have now been obtained, refining its orbital path and moving the date of the asteroid’s close brush with our planet to 8 March.
Ever since it was realised that asteroid and comet impacts are a real and present danger to the survival of life on Earth, it was thought that most of those objects end their existence by plunging into the Sun. But a new study finds instead that most of those objects are destroyed in a drawn out, long hot fizzle, much farther from the Sun than previously thought.
NASA has formalised its ongoing program for detecting and tracking near-Earth objects (NEOs) as the Planetary Defense Coordination Office (PDCO). The office will be responsible for supervision of all NASA-funded projects to find and characterise asteroids and comets that pass near Earth. It will also take a leading role in coordinating efforts in response to any potential impact threats.
