Disposing of Obsolete Satellites by Propelling to the Sun
In addition, to the already decent answers, I'll provide some numbers which will prove the point. Earth's tangential speed in orbit is about $30~km/s$. Let's take a typical satellite mass as $1100~kg$....

Disposing of Obsolete Satellites by Propelling to the Sun
For an object to fall into the Sun, from close to the Earth, its angular momentum, which is conserved in any ballistic trajectory, would have to be reduced close to zero - since its velocity vector ...

Disposing of Obsolete Satellites by Propelling to the Sun
The Earth is moving around the Sun at about 30 km/s so all the satellites orbiting the Earth share this velocity (plus or minus their orbital velocity relative to the Earth).
To fall into the Sun this ...
