WebJun 12, 2024 · I have never taken note of any significant floating point precision jitter on the scale you describe either; Only things like e.g. an orbit line jittering like crazy when you are really far out from its origin, before parenting of the player object switches over from the star to the orbiting entity. WebThis is a far cry from ancient Greek times, when Ptolemy proposed a model of the universe that put Earth right at its center, and the stars all as one orbiting entity. It's also - this may surprise you - a far cry from the 1920s, when astronomers were arguing over whether the Milky Way was the only galaxy (false. come on, 1920!) and whether the ...

WebThe deduction of the expression for $\vec{r} \cdot \dot{\vec{r}}$, where $\vec{r}$ is the displacement of the center of mass of the orbiting entity from the center of mass of the entity which it orbits and $\vec{v} := \dot{\vec{r}}$ is the velocity of the orbiting entity, is critical to the vector analysis which usually accompanies an orbital ... The IAU definitions of planet and dwarf planet require that a Sun-orbiting astronomical body has undergone the rounding process to reach a roughly spherical shape, an achievement known as hydrostatic equilibrium. The same spheroidal shape can be seen from smaller rocky planets like Mars to gas giants like Jupiter. flackwell heath planning
