and hit it hard enough to slightly move it's orbit around the sun? Could this object such as a comet or asteroids physical destruction be hidden by the ocean?

yes, it was surmised that the asteroid that hit the Earth that caused the dinosaurs extinction not only threw up a dust cloud that obscured the sunlight, but also caused the earth to wobble on its axis enough to shift it, helping to cause the ice age.
If it happened today, you needed worry, you wouldn't live through it long enough to worry much,

Define "slightly move." Any *measurable* change in our orbit would require a significant impact event that would not go unnoticed, no matter where it hit.
Edit to add: A large object would not have to actually hit the Earth to change our orbit. Simply passing close to us might cause a measurable change in our orbit or rotation. In fact, such encounters over the lifetime of the Earth have probably had many effects...from the tilt of our axis, precession (wobble of the axis), orbital eccentricity (the degree of ellipticity of our orbit around the sun), and even the tilt of our orbital plane.

Yes and yes.
Even a small meteor vaporizing in the upper atmosphere has some microscopic effect on the Earth's orbit. But an impact big enough to make a significant change to the Earth's orbit would instead smash the Earth into rubble.
There are craters hidden all over the Earth, under the oceans and on land, buried or eroded away.

Moving the earth's orbit would require something that is significant when compared -- basically at least a small planet and not a comet or asteroid. Once the collision occurred, all life would be fried so we wouldn't really care.

A image voltaic flare is only a moderate eruption of fireplace on the floor of the daylight. yet at the same time as they're regularly a pair miles lengthy on the most, and that is particularly huge, it really is not any the position close to getting everywhere even on the point of the Earth(as Earth is ninety 3 million miles from the daylight). So no image voltaic flare can ever, ever cook dinner the Earth.

Yes it is possible. I just read the other day about a large object that is being tracked. They expect it to pass close to the earth in 2036. They have a plan in the works to have a crew - in some type of craft - push it over a period of time further away from the earth.

A reeaaaaaaaaallly huge comet is going to hit the earth on Aug 16 2017. Its power is equal to about 10 MILLION NUCLEAR BOMBS and it is going to turn the Earth to fine powder.

Probably not considering Rosie O'Donnell has fallen a time or two, we're still orbiting and unfortunately, even with her self destructions, she hasn't been hidden by anything yet.

To adjust it's orbit would take a massive impact--more than enough to wipe life out as we know it.

I think comet is too big to hide in the sea...
