An object's ability to bend space correlates directly to the sum of that object gravitational field
the objects found in space include: planets, meteors, meteoritees, comets and stars
It is called an eclipse.
No
With enough thrust to reach escape velocity - the speed needed to counter the pull of gravity and get out into space. Thrust is supplied b the engines on rockets.
The object model is said to reside in object space. we can covert object space units of measure to image space by scaling transformation method.
