I don't care what tech hasn't been invented yet. I want one. --Blacksilver (talk) 02:28, 6 February 2020 (UTC)

Ok, then, Blacksilver: first calculate the orbital period , assuming no external gravitational sources and no atmosphere. And while you're at it, the maximum mass of the satellite before it causes the epicenter to be outside your body. But you have to take the shape of the human body into account: any deviation from equatorial orbit will probably lead to trouble.Cellocgw (talk) 14:43, 6 February 2020 (UTC)

But if we kept them around, that's less material we have to lift into orbit during Dyson sphere construction. *There are too many stars. It's been freaking me out.* (#975) 108.162.216.148 03:25, 6 February 2020 (UTC)

Am I the only one who just assumed that the characters were planet sized beings? --WhiteDragon (talk) 15:03, 6 February 2020 (UTC)

Yes ;) Elektrizikekswerk (talk) 16:39, 6 February 2020 (UTC)
I thought the same, because the sattelite was orbiting science girl. I think this is actually the first time I thought of the alternate solution first. 162.158.74.157 13:22, 10 February 2020 (UTC)

Reads ok to me. Should we take off the the header? Kev (talk) 16:31, 6 February 2020 (UTC)

Agree Elektrizikekswerk (talk) 16:39, 6 February 2020 (UTC)
What's the worst that could happen? 162.158.74.229 19:30, 6 February 2020 (UTC)
Aaand... it's gone. Elektrizikekswerk (talk) 12:44, 7 February 2020 (UTC)

I ran some preliminary calculations assuming this uses orbital mechanics that somehow ignore earth instead of some aerodynamic effects (like the flinks used in Seveneves)... first, acting out the comic I figure that the time between the beginning of the first panel and the beginning of the last panel to be about 20 seconds. Assuming the location of the satellite hasn't moved more than one orbit between each panel, our orbital period is about 20 seconds. I then measured the characters and - assuming Cueball is about 6 feet tall, the little girl is about 4 feet tall. Transposing that onto the second panel, I figure the orbit radius to be about 1.5 feet (0.4572 meters). Here I switch into metric units entirely: the orbital circumference is then 2.87 meters giving us an orbital velocity of 0.1436 m/s. Assuming the girl is an average 7 year old weighing 22.4 KG (as per This Source, and assuming that my use of the orbital equation is correct... the satellite would have a mass of 141 256 782.239 KG.

Nah, you're doing something wrong. The orbit is independent of satellite mass ... 162.158.154.151 13:21, 7 February 2020 (UTC) <--- This is only true when the satellite's mass is insignificant relative to the planet's mass. Otherwise the epicenter ends up outside the planet's radius and we end up with either two bodies of roughly equal mass orbiting a common center or, as in this calculation, the satellite becomes the planet and the poor little girl starts orbiting the satellite Cellocgw (talk) 13:12, 10 February 2020 (UTC)

They also talk about "boosting the sattelite into a graveyeard orbit" in panel 3 which i think is the sattelite boosts from planets which would also make sense or a planet family. 162.158.214.136 21:14, 13 February 2020 (UTC)
