1.   -- Attach nuclear-powered rockets to the asteroid to gradually accelerate it into a new orbit.

2.   After falling earlier this year, Intel Corp., the computer-chip maker, has ascended into a new orbit.

3.   He showed the data to Marsden, who quickly calculated a new orbit showing that the object was probably a moon of Jupiter.

4.   The new orbit will keep it a constant distance from the planet so it can map its entire surface in a consistent way.

5.   We should have known then that he was already shaking it from its axis, rapidly sending it into a new orbit.
