An asteroid as big as the Rock of Gibraltar will streak past Earth on April 19 at a safe but uncomfortably close distance, according to astronomers. Dubbed JO25 and roughly metres 2, feet across, the asteroid will come within 1. It will pass closest to our planet after having looped around the Sun. Smaller asteroids whizz by Earth several times a week. But the last time one at least this size came as close was in , when Toutatis—five kilometres 3. The next close encounter with a big rock will not happen before , when the metre half-mile wide asteroid AN10 will fly by at just one lunar distance, about , km , miles.
It came into view of small telescopes a few hours ago. Image via Planetary Radar Science Group. Enjoy science and the beauty of the cosmos? Please donate to help EarthSky keep going. Want PayPal or to send a check to EarthSky?
A relatively large near-Earth asteroid discovered nearly three years ago will fly safely past Earth on April 19 at a distance of about 1. Although there is no possibility for the asteroid to collide with our planet, this will be a very close approach for an asteroid of this size. An NEO is a near-Earth object. At this time very little else is known about the object's physical properties, even though its trajectory is well known. The asteroid will approach Earth from the direction of the sun and will become visible in the night sky after April
Potentially Hazardous Asteroids PHA are interesting objects, as they are the one that may or did trigger huge meteors and meteorite falls the last big one occured on February 18, , over the Tcheliabinsk region when they come to have an impacting trajectory. But most of them just pass, wave the earth, and go back into other Solar system regions…. This was the case with a small 3 to 6 m diameter one, GM, which was discovered a few hours before it came as close as 10 km from our planet, on April 4th, 10h31min UT! It was then below the altitude of geostationary satellites, but still far enough not to enter our atmosphere. Had it done so, it would have been the source of a very bright meteor but a smaller event than Tcheliabinsk one potentially leading to meteorite recovery may it have fallen on the ground, and not it the water. Discovered on May by the Catalina Sky Survey, this 0. So this time, do not use your naked eye to catch small interplanetary objects, but use a small reflector or refractor, an accurate ephemeris of JO25 , and look at this small bright point rushing through the still stellar sky!

It is currently the smallest, closest, and most stable known quasi-satellite of Earth. Its orbit has an eccentricity of 0.
