Multiple choice.....

Q: Which planet is closest in size to earth?

A: Mercury  B: Venus  C: Mars

Answer: C 🤣

[Mozz71]

Considering Venus and Mars are either side of Earth, it's not the worse answer if someone has little astronomy knowledge.

[ToraToraTora]

It's more local geography mozz. Surely it's common knowledge that Mars is less than 11% of the mass of Earth. Also that the entire surface area of Mars is roughly that of all the land on earth.

[douglas9401]

Common knowledge is often not so.

[naomi24]

Another one that doesn't work.  Are you this boringly big-headed in real life, TTT?

[ToraToraTora]

I knew all this when I was at junior school, I can remember a giant wall chart. Even then I knew venus was known as earth's evil twin. What do the saucepans learn at school these days?

[DTCwordfan]

the saucepans probably become Masterchef participants. It's about time you put your candidacy in for a place in The Chase. Failing this, it's either Masterchef or 'Can't Cook, Won't Cook'.

[Tilly2]

Tut! Not again.

[Mozz71]

Sorry Tora, you're mistaking knowing titbits of information about subjects you're interested in with general knowledge everyone should have. In this case, and without the use of your "superpower", you're wrong.

[ToraToraTora]

what am I wrong about?

[Gizmonster]

I need to ask - what has mass got to do with size??

The question asks which planet is closest in size to earth?

The fact that ////  Mars is less than 11% of the mass of Earth //// is completely irrelevant.

The radius (and therefore the volume) of Mars is just over half that of earth, so the answer given isn't as far out as you're suggesting ......

//What do the saucepans learn at school these days?//

 

Not to be unbearably smug for no good reason maybe?

[Gizmonster]

.... and before TTT corrects me, I know I made an error, the volume is not just over half ..... that's irrelevant anyway, the fact remains that the radius is approx half of earth's.

[newmodarmy]

Yes so the volume would be about 1/8th but as you say the question doesn't specify whether size means volume, surface area or  diameter.

[ToraToraTora]

21:41 well mass is one measurement. Ok volume then 15%, will that do you? I agree size is a general term but the question is asking for comparable sizes and that generally means things like mass, radius, volume, possibly surface area. In any case Mars is nowhere near the size on any sensible measure and venus is close to identical on all of them. So Mars is a silly answer.

[newmodarmy]

Last time I looked on a clear night they all looked about the same size. I'm surprised we've had no comments about Uranus.

[douglas9401]

We wanted to wait until he was finished talking aht ov it.

[THECORBYLOON]

There are various mnemonics for the  order of the planets from the Sun but are there ones for their circumferences and masses?

[renegadefm]

I thought the world is flat, and size didn't matter? Its what you do with it.

 

Seems I have been living under a rock 🤔

[Mozz71]

19:14, about the answer to this question being common knowledge.
