It was very first seen just a month ago.
A tiny blip of light was seen to become moving through the sky by the PanSTARRS1 telescope in Hawaii.
The number-crunching which usually followed was automatic.
The results were uncommon.
This particular object is in an odd place. It’ s moving very fast.
And it’ s in what appears to be a considerably extreme orbit.
Extreme enough not to really be an orbit, in fact.
Findings released by the by the International Astronomical Union’ s Minor Planet Center (MPC) suggest it could came from deep space.
Specifically, it could be the comet that has escaped another celebrity.
“ If further observations confirm the particular unusual nature of this orbit, this particular object may be the first clear situation of an interstellar comet, ” the particular MPC declares.
WHAT IS C/2017 U1?
The PanSTARRS telescope spotted the thing only after it was flung back again out towards the stars by our own Sun.
It’ s not likely to actually return.
It flashed past Earth on 24 million kilometres on Oct 14.
Many eyes watched it carefully, keen to determine exactly what it was.
Their attention was piqued by where this had come from.
Most objects orbiting the Sun do so along a common airplane: the planets, dwarf planets plus asteroids mostly swing around within roughly the same way.
This one appears to came down on the plane from 122 levels, from the direction of the star Vega, in the constellation Lyra. And its path failed to indicate the curved ellipse typical of clockwork-like returning comets.
Greatest guesstimates make it a comet of about 160m diameter, with a surface reflectivity (albedo) of about 10 per cent.
The thing has just been through a close call (in Solar System terms): it emerged within 38 million km of our own star before its momentum as well as the Sun’ s gravity hurled it in return outward.
Normally such a close pass will be fatal. But C/2017U1 was venturing too fast for the Sun’ s high temperature to consume it.
It was moving at 26km per second when first noticed.
Astronomers are now attempting to refine their findings and data to pinpoint where it came from. If it truly features interstellar origin, the next task would be to find which star it is likely to get come from.
At the moment, it appears to have been someplace in the direction of the star Vega.
It’ ersus also likely to have been wandering, on your own, in deep space for a quite, very long time.
Vega is a relatively close neighbor of our Sun at 25 lighting years distance. At the speed it’ s travelling, it would take regarding 1 . 7 million years in order to cross the interstellar divide.
