Every daylight it seems another natural calamity could convey about the apocalypse . Volcanoes . Earthquakes . Hurricanes . Sometimes that list includes asteroids . But despite exaggerated newspaper headline from theusualsuspects , there ’s no need to concern about the latest nearby asteroid approach .
( 3200 ) Phaethon is a rockfive kilometersin diameter with an oblong orbit that intersects Earth . It ’s scheduled to make a nearby approach on December 16th . You ’ll probably discover more concern - huckster shouting about it until then , but it ’s not a rock candy you should worry about during your lifetime .
scientist first observe ( 3200 ) Phaethon in 1983 , fit in to a NASA - Jet Propulsion Laboratorydata sheet . Its eccentric crosses our own planet ’s celestial orbit , put humans in a pretty precarious place . It ’s been separate as a “ Potentially Hazardous Asteroid ” for that reason . But the name is a tad misleading .
“ [ Potentially Hazardous Asteroid ] is not a very good term because it implies that things are move to come crashing into us right away , ” Matthew Holman , interim managing director of the International Astronomical Union ’s Minor Planet Center told Gizmodo . “ It ’s over recollective period of time of time — basically , this is more of a plausibleness affair . ”
Holman went on to explain that “ Orbits of asteroids are changing on the timescale of hundreds or thousands of years , perhaps farseeing . It ’s really not a statement about urgency . It ’s a statement of plausibility — it ’s something that could ever have a collision trajectory towards Earth . ”
Holman did n’t speak directly to ( 3200 ) Phaethon , but discussed that scientist consider these thing closely . The community tracks and posture the arena of any potentially dangerous rocks , like they did for 99942 Apophis which briefly caused a scare about adecade ago . Scientists at agenciesdesigned to worry about these thingssuch as NASA would distinguish you if ( 3200 ) Phaethon was truly a threat .
The rock will pass away a fiddling less than 6,500,000 Admiralty mile from the Earth on December 16th , around afifth of the distancefrom Earth to Mars at its close . Mars is very far away — but you still might be able to observe the asteroid witha telescope . The next clock time it will come any closer is 2093 when it will go past around 1.85 million miles away — still seven time further than the moon . You will most likely be dead by then .
( 3200 ) Phaethon is still neat and foreign . It produces a meteor shower here on Earth called the Geminids , but unremarkably it ’s comet , not asteroids , that cause these event . There are a few hypothesis as to why that might be , but it’sstill a mystery .
Anyway , take a schnorchel and enjoy the holiday time of year . There is no need to worry about an asteroid .
Update 12:15pm : We spoke to Gareth Williams , astrophysicist from the Harvard Smithsonian Center for Astrophysics , for a little more detail . Determining whether a large shooting star will strike is never an easy yes - or - no resolution , he sound out . As before long as an asteroid is discovered , there ’s a magnanimous , unsettled area where scientist recall it will travel , a neighborhood that may or may not include Earth . After subsequent observations , that part will become smaller , and an impact is rule out once Earth is out of doors of that area .
But scientists have already mock up this new shooting star jolly well . “ ( 3200 ) Phaethon is not an object we necessitate to occupy about at this sentence , ” say Williams . “ Over tens of thousands of years the orbit will be perturbed by giant planets and the Earth , so the orbit could come closer . ”
So we might not know a lot , but in this case , we know this meteor is not a grownup deal .
