Astronomers eager to study asteroid during 2029 close flyby of Earth
Small asteroid is Earth’s constant companion
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.”
Asteroid 2013 TX68 won’t hit Earth, but will get close
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.
