Pluto and definition of planet
... Pluto’s orbit is very elliptical and inclined. When he is closest to the Sun, Pluto is 39.5 AU (one AU has 149.6 mil km) form Sun and when farthest he is 49.3 AU from Sun. Consequences of this are large variation of average temperature on surface, from -240°C to 218°C. When going away from Sun, Plut ...

The smallest dust grains then orbit with the gas; larger grains orbit more quickly (since surface area increases less quickly than mass). Since dust grains are moving at different speeds, they tend to collide with one another, an ...
