It would need the planetary remains to
have been in a molten state for the
sphere to form .... and nothing in the
'Doctor Who' episodes has looked molten
to me, Tim.

The gravity of a planet of half Earth's
mass should be enough to collapse it into
a spheroid shape, regardless of
molteness.

The Gravity of a Planet of Earth's Mass *IS
NOT* enough to collapse it into a spheroid
shape!!
Hence Mt Everest sticking well and truly
above the Earth's surface average or the
Marians Trench sinking well and truly below
the Earth's surface average ...... for
several Million years!!

When we say 'spheroid' we don't mean as
smooth as a billiard ball! If you want that,
look at neutron stars. :-)
Nobody claimed their wouldn't be mountains or
valleys.
The diameter of Earth is about 12,756
kilometers. Highest mountain is 8,848 meters
high. That's about 0,069363437 percent of the
diameter. Hardly noticeable.

https://theconversation.com/ive-always-wondered-why-are-the-stars-planets-and-moons-round-when-comets-and-asteroids-arent-160541

So minuscule differences, so should have been
easy to obliterate!! ;-P

Oh ?-)

The mountains are hard.

And yet, something as "soft" as water can cut
straight through them. Give the elements enough time
and mountains will yield!

But on Earth, new mountains rise.

Yes, through platetectonics and vulcanism. Earth is a
dynamic planet. Features come and go, that's a continues
process.

When was the last Time a new mountain rose?

Wasn't there a Volcanic eruption about fifteen years ago off
Iceland or Greenland that resulted in a new island being
created??

I have heard of China creating its own islands!

Through what process?

Steel islands.

So, made of steel and then sunk?

What was the name of the Planet-making Planet in HHGG??

You tell us!

Magrathea is an ancient planet located in orbit around the twin suns
Soulianis and Rahm in the heart of the Horsehead Nebula.

It was the home of a new form of specialist industry: custom-made, luxury
planet building.

I knew someone afd-a would be of help.

I was deliberately ignoring this crosspost tbh. "The Doctor" got their
answer on the original thread without us anyway, but moreso, is just
a generally awful person - completely failing to live up to the
fictional character whose name they've appropriated.

Not at all fun fact: one of their first interactions with afda was to
question the genuineness of a post by Douglas Adams, thus giving rise to
the story that Douglas was hounded out of here by people questioning the
genuineness of his posts here (if there have ever been other similar
questionings, I've not found them)
