Curious as to the effect this planet would have on its sun if it spirals into it.
If the planet has a similar composition to Jupiter of largely hydrogen and helium, would that be enough to kick-start a new phase in the star?
Astronomers have discovered a hot Jupiter-like exoplanet with the shortest orbital period yet: a year on this large puffy world lasts just 18 hours. “We’re excited to announce the discovery of NGTS-10b, an extremely short period Jupiter-sized planet orbiting a star not too dissimilar from our Sun,” said James McCormac, a …
Venus suffers from the horrendous greenhouse effect however, trapping heat..
Mercury varies greatly on the sunny side and dark side, because it has no atmosphere. A quick google and the sunny side is 430C. The cold side -180C.
I guess it would be hotter but depends on the what chemical break down of the planet is and whether it reflects heat away or keeps it.
Venus has a lot of problems - rotates the wrong way and takes 116 days longer to do it than this exoplanet takes to get round its entire sun. Also the atmosphere at the surface is 93 times the pressure we have on earth.
So sorry Europe it may be the final countdown but Venus is not a good destination to head for....
Of course being Jupiter sized, it must also have a Jupiter type gravity, which coud be enough to keep itself intact....
But over time, it's local star (being bigger/heavier) will no doubt win the battle.
I suspect that we're living at a time after which this Jupiter-like planet has moved orbit towards its Sun but unlike our Solar System, there's not been any other celestial body" around to fling it back outwards.

I'm afraid that if Jupiter decided to move closer to the sun there is nothing anybody could do about it.
Mars? Earth? Venus? Mercury? All those are pebbles compared to Jupiter, it would toss them out of their orbits without even noticing. The only planet (barely) able to compete is Saturn (3 times lighter than Jupiter though), and its orbit is further away than Jupiter's anyway.
To resume, let's hope Jupiter is quite happy with its current orbit, lest we experience the infamous "elephant in a doll house" effect...
