Re: What are they going to do with the heat?
Radiation is radiation. There's no "inefficient" way of radiating. You might be thinking of convection.

Don't forget that the force due to gravity is a function of the masses of both objects, so the attraction of Gas Giants to their sun would be greater than that of small comets (assuming a giant has a giant mass, despite being gas), even at that great distance.
After all, galaxies manage to attract each other too at relatively vast distances. Gravity goes on forever, in theory.
I wonder if it's related? One W10 laptop in my house has recently and intermittently begun throwing up a dialog box stating that Wifi is switched off, when it clearly isn't.
Ethernet works, it just doesn't want to use the Wifi.
Rebooting didn't help reliably but sometimes disconnecting and reconnecting the (not actually switched off) wifi does work.
Leaving astronomers very interested.
FTFY
Why do some news stories feel that scientists have to be bewildered, baffled, etc, when observing something not seen before.
As credited to Asimov (possibly): "The Most Exciting Phrase in Science Is Not ‘Eureka!’ But ‘That’s funny …"
According to the BBC story:
"Emirati and US engineers and scientists worked alongside each other to design and build the spacecraft systems and the three onboard instruments that will study the planet."
and
"considerable work was also undertaken at the Mohammed Bin Rashid Space Centre (MBRSC) in Dubai."
and quoting the University of Boulder, Colorado LASP spokesperson:
"Their propulsion engineers have now done it and they know how to do it the next time they build a spacecraft."
So let's not take it away from them. Anyone putting together a Mars mission for the first time is going to need to lean heavily on others' experience.
The only planets that change shape, "much like the moon" are Venus and Mercury, because they are between us and the sun, also "much like the moon". The shapes seen are explained by the fact that they are round "much like the moon".
The other planets we can see (yes I have several telescopes and have verified this) are always seen as round, because they are.
It seems that many people don't wear watches these days because they think it's quicker to get their phone out and view the time than tilting their wrist. These people may not agree that this kind of device is useful as you said.
But these people probably would just use a smartphone app.
My issue with this is that I don't leave Bluetooth on all the time.
I met Douglas in a bookshop in Birmingham when I was a student. He was there with co-author Mark Carwardine for a signing of Last Chance to See. A group of us from the RAG society heard he was there and decided to go down dressed in suitably menacing attire and flan him with a plate of shaving-foam, as was the habit back then, as part of the charity fund-raising we did.
To his huge credit he was well up for it and afterwards signed my copy of the book "with deep hatred and resentment".

2. Ask the product designer, not the end-user
3. That would have spoiled the story. By the way what's the difference between an "apartment" and a "flat" in your world? In mine, apartment is an up-market (or left-pondian) word for flat.
4. RTFA
5. I wouldn't bother reading any more of SFTW if you don't get satire.
"Fast charging stations are for the development version of electric cars. Production electric cars will have easily replaceable battery packs constructed to a universal standard."
That's the sensible solution but it doesn't seem to be the actual case. As far as I know, no production electric cars have this type of battery pack nor are there places to do so.
Unfortunately the focus, in the UK at least, seems to be on increasing charging points rather than changing to replaceable batteries.
