Modal pop-up when selecting a celestial body

[amgauthier1992]

• Create contexts (celestial body and modal?)
• Figure out a way to dynamically attach planet data upon initial render to each planet mesh (useEffect + refs?).
  • Look at this
• Create type defs/structure for data itself (figure out what data we want to display about planets when opening modal)
  • mass, diameter, gravity, name, distance from sun, surface temp etc.
• Create MVP modal that spits out planet data
