and predicted that it was due for an encounter with our solar system in around 29,000 years. While this may seem a long time in human terms, it is a relatively short period cosmically speaking. For instance,While the sun's fate is likely sealed, new research has revealed that our planet at least won't have to worry about being decimated by the chaos caused by runaway white dwarf WD 0810–353 after all.
WD 0810–353 might offer a preview of what the sun will look like at that time when it comes to within around half aWhile this seems like anything but a close encounter, it is close enough that the gravitational influence of WD 0810–353 could disturb theThe Oort cloud is located between 2,000 and 100,000 times the distance between Earth and the sun from the solar system's central star.
"Unusually, this old white dwarf also has a huge magnetic field," explains Eva Villaver, an astronomer at the Astrobiology Center in Spain and co-author of the study."In astronomy, magnetic fields are crucial to understanding many physical aspects of a star, and not considering them can lead to misinterpretations of physical phenomena."
