What happened exactly, a comet was impacted by an asteroid? What distance from earth?

The comet was hit by a spacecraft launched by the USA, for
the purpose of stirring up dust in order to learn it's
composition. It hit at the speed of 23,000 mph, which
sounds fast, but is only the same speed as the rotation of
the earth.

The comet is about the same distance from us, as the Earth
is from the sun. That makes it about 8 light-minutes away.
Close on the scale of previous solar system explorations.
It is in the general direction of away from the sun, from
our perspective.

Of course the person who made this possible was Isaac Newton,
who discovered 400 years ago that you could chart the position
and velocity of a comet by making careful observations from
the Earth.

Can't you feel our souls ignite
Shedding ever changing colours,
in the darkness of the fading night,
Like the river joins the ocean,
as the germ in a seed grows
We have finally been freed to get back home.

It was quite an amazing feat really. Like hitting a bullet with another bullet. Now I hear some "seer" wants to sue do to the astoriod being hit and mis-aligning the universe. She can no longer make predictions.
A good plan, violently executed now, is better than a perfect plan next week. A pint of sweat, saves a gallon of blood. No poor bastard ever won a war by dying for his country. He won it by making other bastards die for their country.

I would guess that Kepler's discoveries in optics, mathematics and
especially astronomy must have directly inspired Newton's work.
But Newton went far beyond Kepler. After all, predicting the paths of
comets was just a side effect of his theory of universal gravitation.
