How long did it take for Venus to form?

so divide this by speed of light 300,000 KM.sec. 108200,000/300,000= 360.6 seconds or 6.0 minutes.

I am assuming a Hohmann transfer, because it is the lowest energy transfer. The spacecraft does a $Deltav$ burn from low Earth Orbit to begin its free fall around and...

We observe that it happens, but too slowly to measure on human timescales. Many millions, but probably not billions of years would be a sensible estimate.

Considering that we do not have a rocket to go at such a distance it is difficult to say. We can give an estimation based on the Moon mission. The...

Phoenix communicate to earth through Mars Reconnaissance Orbiter which in orbit around Mars. Light travels through vacuum at speed of 300,000 kilometer/second. 1 AU=149000000 kilometers. so aproximately 12 minutes...

A full set of phases, like , can only be had if the object we're talking about, can get between the light source (=Sun) and ourselves. Planets farther away from...
