Yes, reminds me of that sf movie/tv show trope where the invaders are coming in from outer space, we see them passing Saturn, then Jupiter, then Mars, then the Moon, on their approach to Earth. As if the planets were all neatly lined up based on their orbits. Because in the minds of most people that's how it "should" look to zoom in from outer space to our planet. Whereas what this is demonstrating is that on average the planet the invaders would be most likely to pass close to on their approach to Earth/Moon system would be Mercury.
- Beldin 8y agoThis is complete speculation: If you're coming from outside the solar system and want to end up orbiting earth, you probably need to change your delta-v significantly. Perhaps passing by the gas/ice giants isn't that bad a way of doing that?
