Which planetary orbit is closest to Earth’s? That’s what I think people are meaningfully thinking.

- ianai 3y agoVenus by that measure.
- svachalek 3y agoYup, that's equivalent to the delta-v definition afaik. (Venus)
- Symmetry 3y agoIt's close equivalent. It's easier to go inwards than outwards in terms of delta-v because orbits further out move more slowly. So if things were a little different the orbit of Mars could have been closer to Earth in terms of distance while Venus would still be closer in terms of delta-v.
- xvilka 3y agoOnly if you want one-way trip. In case of the two-way trip, Mars could be still closer due to lesser Sun gravity influence that needs to be compensated.
