I meant whether we are farther away from the sun or not. As in, would it take less energy to hit the sun if we started from Mercury.

But now I realize that it’s our momentum given earths orbit. So I guess it would be harder from mercury cause it’s going faster?

    Nope, it'd me much easier from Mercury. A higher orbit has more energy. A space ship has to speed up to increase it's orbit.

    Think of it like the old expression about what an orbit even is: You're still falling same as always, you're just moving to the side fast enough to always miss. Earth is 'missing' the Sun by a whole lot more than Mercury is 'missing' the Sun.
