Wasp-18b the planet that should not exist

[FGFG]

<< Wasp-18b is a planet distant 325 light years from Earth and big ten times Jupiter but, orbiting at 3 millions kilometers from its star, it will be incorporated in "just" a milion years.

Its discoverer, Coel Hellierm writes that Wasp-18b is dancing a "death tango" with his godmother. According to Nature its orbit lasts less than 24 hours and the extreme closeness to its sun is already making it evaporate: it has been calculated that its surface reaches 2100 Celsius.

Wasp-18b is a very particular planet, because of its dimensions and its orbit, according to Nature, it would be contrary to the lows that normally rule the motions of celestial objects. Theoretically, Wasp-18b shouldn't even exist... >>

P.s. I translated it from an Italian article because I didn't find anything in English. This is why there isn't any link yet.

Edit: grammatical errors...

That was in a german newspaper too.

Interesting.
It has probably formed further away from the star and gotten gravitationally disordered by something else, throwing it into a close orbit around the star.
What do you think?

its called planetary migration.

It might collide to the star in a million years later or so...

In eleven million years. or 11 million years.

We don't need any clarification . The size has nothing to do with mass. It'd be highly logical to infer that its a gas giant, because gas expands to higher volumes more easily with heat. The volume has to do with inflation due to its extremely close orbit to the star. I wonder what it would look like when the star touches it  if it has the right composition it could explode in a fire ball!

If it is less heavy and less dense it's strange that it remains in orbit without bowing up.
If it had the right composition it wouldn't exist now because it's so near that would have already exploded

Well I would need an artist's interpretation to imagine that!!!

No, that's Phobos colliding with Mars.
