Then make the mass cut-off bigger: 0.01 Earths. Kids have to deal with the alphabet and the elements... I think they can count past the number of fingers... By the 'clear the orbit criteria', Earth wasn't even a planet until after bits of Theia became a moon (planet-sized moon). It's...

Roundness and orbit clearance are potentially dynamic and definitely subject to interpretation (is Vesta 'round enough'?). Mass, less so . Pick a mass and stick with it. I'd say 0.001 Earths ~6x10^21 kg.

I think you mass at takeoff is either low by a factor of ten or represents the unfueled mass.
