It's travelling at around 80km/s radially according to the paper so that sounds about right. Almost all the velocity is radial, only 3km/s is observed tangential to us.
In perspective, it's only around 4-5 times faster than Voyager 1 or New Horizons.
- eyko 12y agoIt's also _speeding_ away (no info on how many km/s per year faster it is?). It could've been much slower 70.000 years ago.
- mangeletti 12y agoSince it is moving away from a large body of mass, namely, the day star, it's likely that it has been decelerating over the past 70k years, meaning it would have been moving more quickly when it passed by.
