I tried to copy the whole calc. But I guess it’s not working too well since I’m on my phone.
Here.
Panel Height: 301 pxPlanet Height: 531 px/12,756,000 mSolar Disk Height: 86 px"Astronomers have calculated the extent of the habitable zone for many different types of stars. For example, at present, the habitable zone of the Sun is estimated to extend from about 0.9 to 1.5 astronomical units (the distance between Earth and the Sun)."0.9 AU = 134638083630 meters = dSunNow for the rosche limit calculation.d = 2.4 * 6,378,000 * (5,510/7750)^(1/3)d = 13661940.473410 meters12756000 = R/((696000000 - R)/(134638083630 - 13661940.473410)Plug that into an algebra calculator and you get a radius of 65941.489210900 metersDiameter: 131882.97842180 meters
Panel Height: (28 px ÷ 234 px) × 131882.97842180 m = 15780.869212864 mPanel Thickness: (13 px ÷ 102 px) × 15780.869212864 m = 2011.2872526199 mSolar Disk Volume: (π65941.489210900^2)×2011.2872526199 × .7 (assuming 30% hollowness) = 1.92326671560E13 cubic meters or 1.92326671560E19 cubic centimeters
