And who is going to trade with who?
Wouldn't it be nice if space exploration could be a little bit more altruistic and a little less profit based.
What space body should be colonized first, if any

You are not wrong, but the earth weighs 5.972 × 10^24 kg. It would require transferring an awful lot of stuff to make a noticeable diffference. Many tons of material are added to the earth every year due ot meteorites.
If there is a lot of easily accessible gold on Mars then gold would lose its rarity value. The value of the gold in Fort Knox and the Bank of England etc would collapse with unforseeable consequences to the world economy!

True. Thank God for that, or else we could be surprised to find ourselves falling into the sun after enough asteroid hits.You are not wrong, but the earth weighs 5.972 × 10^24 kg. It would require transferring an awful lot of stuff to make a noticeable diffference.
Many tons of material are added to the earth every year due ot meteorites.Again true. And many tons of material are lost from the earth every year due the atmosphere bleeding off. Nice balancing no?
If there is a lot of easily accessible gold on Mars then gold would lose its rarity value.
Not necessarily. If it was tremendously expensive to transport back to earth, gold might even increase in value. And gold being so heavy, that might well be the case.

That's what the formula says, Cleetus, but I know you have no clue about formulae.Which shows that if the mass of Earth should increase, the orbit would remain the same right?
Its wonderful that you will be so publicly stupid willingly. Ah, militancy and ignorance, mixed in with crippling bitterness, what fun.

Venus is a good candidate if we develop the technology for floating habitats, because simulating earth-like gravity is much harder to replicate using technology on the scale of a planet. Low grav environments like Mars and the Moon have debilitating effects on the human body.

Tell us again genius.

Gm1m2/r2 = m2rω2
So ω2 = Gm1/r3
where ω = 2π/T where T is the time for a complete orbit
Note that m2 (the mass of the planet) cancels out.
