The remnant of a dead star predicted to cannonball through the outskirts of the Solar System is going to do no such thing after all.
On reexamination, a white dwarf star just 36 light-years from Earth named WD0810-353 has turned out to be pretty normal. Its only claim to strangeness is its powerful magnetic field, according to a team of astronomers led by John Landstreet of the Armagh Observatory & Planetarium in the UK.
It's this magnetic field, the researchers say, that led scientists to misinterpret the trajectory of the star through the Milky Way galaxy...
Nevertheless, WD0810-353 is interesting in and of itself, and could help scientists better understand how white dwarf magnetic fields evolve as they cool.
The Solar System doesn't exist in isolation. It belongs to a vibrant and fascinating stellar community, with every object on its own orbit or path around the galactic center. Some of those paths could result in encounters with other stars – including our Sun...
A paper published earlier this year, written by astronomers Vadim Bobylev and Anisa Bajkova of the Russian Academy of Sciences in Russia, details a handful of candidates for close encounters in the future.
The most interesting of those was a white dwarf named WD0810-353. Using data from the Gaia mission, Bobylev and Bajkova calculated WD0810-353 is traveling at a blistering 373.7 (232 miles) kilometers per second.
They also calculate that, in just 29,000 years, WD0810-353 is going to pass within 0.49 light-years of the Sun. That's a distance of just 31,000 astronomical units, which would bring the white dwarf within the Oort Cloud – a population of small, icy bodies estimated to orbit near the Solar System's boundary – scattering the frozen blocks towards the inner Solar System as comets.

36 Light years away means it would take forever to get here. The horror!
That doesn't sound good.
For reference, Neptune is 30 astronomical units from the sun, so this star will pass our sun 1,000 times the distance to Neptune.
That's mighty close. Will earth have two suns? Will the sun capture this star and create a binary star system?
Climate change has caused this. We’re all gonna die again. Where’s Greta.
There is so much we little Earthlings know nothing about.
Our science world is full of speculation with science to back it up.
Stuff so far away, we only know what was happening centuries ago, and yet the so called ‘smart ones’ can play god — false god.
Those dead stars are quite the pranksters
The bigger issue would be if the star causes bodies in the Oort cloud to drift into the inner solar system and hit the Earth.
Hopefully in 26 thousand years we will be able to deal with that.
[[Where’s Greta]]
She’s busy deleting her tweets about the earth ending this year.
No, no inanimate object *tricked* anyone into coming to the wrong conclusions.
The *scientists* did that all by themselves because in their arrogance, they think they know everything already.
I remember a panicky article about a black hole “pointing directly at Earth” —Scitech daily, Nov 30, 2022.
My retort was “Black holes don’t point”.
No, that’s metmom.
They can pants ya with a danged magnetic field as they race through the Solar System. The rest of the nearby stars just point and laugh.
False.
lol- when you least expect it too :)
That would be a REAL BIG issue if the Clinton and Biden Crime Families have hidden their bodies in the Oort cloud.
There’s a lot of stars out there.
And even more directions.........................
