In this week's questions show, I explain why you could have a steam-powered rocket, how often spacecraft have crashed into asteroids and comets, and why a red supergiant star actually has a very low surface gravity.
02:42 Could you build a steam-powered rocket?
04:48 Have any probes crashed into asteroids or comets?
06:47 Surface gravity of UY Scuti
08:57 Will we ever send humans to the surface of Venus?
11:08 Lol
11:24 Does Venus have a magnetic field?
12:22 Longer guest interviews?
14:09 Save the shoutouts to the end
15:55 Could a probe float at the surface of Venus?
16:47 Where do I get my news?
20:29 Why don't meteor showers hit satellites?
21:57 Why not add a module to James Webb?
Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week, and answer them here.

Heh, Jupiter is HUGE. That would be well inside the Roche limit of Jupiter though, wouldn’t it? So you couldn’t ever actually have that view from a reasonably sized body.
As far as I can remember Io orbits at about 420,000km, So another 40K to the Roche limit? I’m not sure what effect the increased size of the earth would have, but we might be able to orbit Jupiter at that distance.
If not, there would still be some serious tidal effects, assuming we still had a 24hr day…
imagine kilometers high waves sweeping whole continents every day…after few years (or centuries?), there would be no land left, just a water world eventually freezing out to Europa’s big twin moon.
With Neptune and Jupiter these planets would not be orbiting the Earth so much as Earth would orbit them.
LC
And even with mars we may be orbiting a common center of Gravity that is in space, similar to Pluto and Charon.
What? No Uranus, Neptune, Pluto, Quaoar or Sedna?
Oops… Neptune WAS included..
Quasars, SMBH AGN, Blazars, Radio, Seyferts, Spiral, Active Galaxies all are the same phenomena dependent upon the viewing alignment direction of the observer. NASA and ESA say it is believed by most astronomers today by an evolving unified galaxy model, the most accepted is that blazars are nearly directly aligned jets. Quasars are all sky and where less dust obscures the AGN at a 45 degree 3D orientation. Radio galaxies conceal the AGN aligned with their torus of gas and dust. We would appreciate comments about our Holographic Galaxy Unified Model.
Firstly I hope this and your comment are deleted. It is blatant advertising, from someone who is not even interested in the topic here!
Really. What has this to do with planetary scales?
I can only conclude you don’t know the difference, which then means you don’t know what you’re talking about, and you’re wasting everybody’s time. If do know the difference, the your just as silly.
So if you want to “appreciate comments”, here’s one, its simply balderdash!
Have a nice one… whatever your name is!!
