All the planets in the solar system can fit between the earth and the moon

    Australia is wider than the moon. If earth had the size of a football (soccer), the moon would be about 7m away. If the sun had a diameter of 1m, Neptune would be 5.6km away. In that scale model, the next star would be placed in the outer planets. Space is insanely big.

    I’m confused what you mean by wider. As far as I can tell Australia is about 4000km wide and the moon’s circumference is about 11000km

    EDIT: it’s late and I am dumb, I take it you mean the moon’s diameter! 3474km

    I looked up the circumference of a football and it said about 70cm. As the moon is about 10 times the circumference of the earth away, that'd put the moon at 7m away.

    A 70cm diameter soccer ball (>2 ft across) would be kinda fun. Except headers the CTE would be even worse!

    All Very true facts. I admit I was and am still taken aback by the measurement and extrapolation of linear distances using... circumference.

    That's insane when you really think about it.
    I doubt we'll ever leave our system

    If you count Voyager, we already have.

    Otherwise ... Yea, I'll be surprised if society in general even makes it to 2100 unscathed.

    Voyager is fantastic, but it’s still way, way closer to the solar system than anything else.

    An excerpt from Wikipedia:

    At this rate, it would need about 17,565 years to travel a single light-year.[78] To compare, Proxima Centauri, the closest star to the Sun, is about 4.2 light-years (2.65×105 AU) distant. If the spacecraft was traveling in the direction of that star, it would take 73,775 years to reach it. Voyager 1 is heading in the direction of the constellation Ophiuchus.

    Gonna need a fact check on this one.

    Are we counting the gas of Jupiter or just the solid core? Same for the others

    Actually, Jupiter doesn't have a solid core the way you think! The gases just get so dense at the core that it starts to behave like a solid. You couldn't, like, blow away all the clouds and have some rock to wander around on.
