A newly found planet orbits so close to its parent star that it's close to being torn apart by the tidal forces induced by gravity.
This 'hot jupiter' alien planet is dancing with death with its 18-hour year : Read more
Another interesting exoplanet report and hot Jupiter type. The MNRAS abstract states "NGTS-10b orbits its host at just 1.46 ± 0.18 Roche radii, and we calculate a median remaining inspiral time of 38 Myr and a potentially measurable orbital period decay of 7 s over the coming decade, assuming a stellar tidal quality factor Q′sQs′ =2 × 10^7."
An orbital decay rate of 7 seconds over the next ten years and spiral into the parent star in 38E+6 years. Here is some more stats on NGTS-10b exoplanet,
Planet NGTS-10 b The host star age is shown as 10.4E+9 years old, a smaller K5V main sequence star. The current orbit measurements suggests the exoplanet will die in 38E+6 years, falling into the host star, yet the host star can be older than 10E+9 years old. If the exoplanet formed in situ, there is a serious age problem with the H-R diagram age. The exoplanet could be rotating on its axis like Jupiter too, perhaps 10 hour period or close to 15.7 km/s because it has a larger diameter than Jupiter too. Exoplanet research is getting very interesting.
