From the article:
"This is because it is being yanked back by the star's staggering gravitational pull - which is about 27.9 times that of Earth"
I would have guessed the Suns gravitational pull much more than 27.9 times that of Earth.
Not so:

In our apartment in central Beijing, we fight a daily rearguard action against entropy. The mirror on my wardrobe came off its hinges six months ago and is now propped up against the wall, one of many furnishing casualties. Each of our light fittings takes a different bulb, and a quarter of them are permanently broken.

In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by three different detectors, marking a new era of greater insights and improved localization of cosmic events now available through globally networked gravitational-wave observatories.

There's this:
"In the production of vases, which are generally rotationally symmetrical, the use of the lathe suggests itself and circular striae on unfinished work pieces seem to point in this direction, but the employment of the lathe is not documented before the middle of the first millennium BCE.
