Small Asteroid Is Earth's Constant Companion




https://www.nasa.gov/feature/jpl/small-asteroid-is-earths-constant-companion


A small asteroid 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.

As it orbits the sun, this new asteroid, designated 2016 HO3, appears to circle around Earth as well. 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."

"Since 2016 HO3 loops around our planet, but never ventures very far away as we both go around the sun, we refer to it as a quasi-satellite of Earth," said Paul Chodas, manager of NASA's Center for Near-Earth Object (NEO) Studies at the Jet Propulsion Laboratory in Pasadena, California. "One other asteroid -- 2003 YN107 -- followed a similar orbital pattern for a while over 10 years ago, but it has since departed our vicinity. This new asteroid is much more locked onto us. Our calculations indicate 2016 HO3 has been a stable quasi-satellite of Earth for almost a century, and it will continue to follow this pattern as Earth's companion for centuries to come."

In its yearly trek around the sun, asteroid 2016 HO3 spends about half of the time closer to the sun than Earth and passes ahead of our planet, and about half of the time farther away, causing it to fall behind. Its orbit is also tilted a little, causing it to bob up and then down once each year through Earth's orbital plane. In effect, this small asteroid is caught in a game of leap frog with Earth that will last for hundreds of years.

The asteroid's orbit also undergoes a slow, back-and-forth twist over multiple decades. "The asteroid's loops around Earth drift a little ahead or behind from year to year, but when they drift too far forward or backward, Earth's gravity is just strong enough to reverse the drift and hold onto the asteroid so that it never wanders farther away than about 100 times the distance of the moon," said Chodas. "The same effect also prevents the asteroid from approaching much closer than about 38 times the distance of the moon. In effect, this small asteroid is caught in a little dance with Earth."

Asteroid 2016 HO3 was first spotted on April 27, 2016, by the Pan-STARRS 1 asteroid survey telescope on Haleakala, Hawaii, operated by the University of Hawaii's Institute for Astronomy and funded by NASA's Planetary Defense Coordination Office. The size of this object has not yet been firmly established, but it is likely larger than 120 feet (40 meters) and smaller than 300 feet (100 meters).

The Center for NEO Studies website has a complete list of recent and upcoming close approaches, as well as all other data on the orbits of known NEOs, so scientists and members of the media and public can track information on known objects.

It's amazing they found it at all considering that it never gets closer than 38 times the distance of the moon and it is no more than 100 metres in size.

You never really see space junk or certain satellites, unless you are really looking for it. So, something only 100 metres in size and so far away would be easy to miss.

That is a pretty big object to just find out about, were the astronomers on a coffee break, maybe it will become another moon of ours.
If a big asteroid comes from behind the sun we are gone, we are in the lap of the gods.
If a big asteroid comes from anywhere we are gone, NASA needs to take steps to defend the human race from the gods.

It is something that has already been thought about
What exactly do you suggest that they do? Call Bruce Willis?

If something 100m in size were to be hidden behind the sun I would have thought the sun would capture it.

Blow it off course, if it came from behind the sun it would probably take only three days to reach us, boom.
The asteroid belt is full of big rocks subject to various gravitational influences and could collide and come our way, if a comet came our way boom, 18000 meteors hit us each year,  the big one is around the corner.

It would depend on its trajectory. From what I can gather.

I sat in the grandstands of Suncorp Stadium to watch the Mighty Qld Maroons play the Moronic Multicultural New South Wales Boos in State of Origin. As I sat in the stands, I marvelled at how small the field (100 metres long goal post to goal post) seemed so insignificant from a perspective being up in the stands. I have seen helicopter footage from 500 metres in the sky, and the entire stadium did not look that big.

So, an object 100 metres in length would not likely be found orbiting the earth from a great distance.

It is estimated that the one that wiped out the dinosaurs was ten kilometers across, that would look pretty small in comparison as well.

An asteroid 10km across would be capable to wipe out a city and surrounding areas, if it impacted with Earth. But it would take a much larger one to cause a worldwide extinction level event.

Depending on the region of impact.  If the asteroid defile gravity, and happens to land in Antarctica, perhaps 10 to 20kmg would do it.

THe KT extinction was likely a 10 km asteroid

With so much space junk up there circling around the planet...
