Jupiter is twice the mass of all the other planets combined. It is more useful and more accurate to refer to the mass of planets, and not to their weight.

Planets
In our solar system, the planet with the most mass is Jupiter. So, if the planets could be arranged with their centers all at the same distance from, say, the center of the sun, then Jupiter would be the heaviest in that situation.
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
All of them

All the planets revolve around the Sun.
At the "aphelion".

Regretfully that would be me. Serious answer: It's the planet Jupiter. Strictly speaking mass isn't "heavy". It's "weight" that can be heavy. So, "Jupiter is the greatest mass" is a better way to say it.

Jupiter has the largest diameter, volume, and mass.

A frozen ball of dust and gas revolving around the sun could describe the planet Pluto. The planet, Pluto, was downgraded to a frozen ball dust and no longer considered to be a planet to scientists and astronomers.
I wouldn't say the planet Uranus matters, but it does in some ways, for it is a planet made out of gas and may have an impact on the gravity of Earth revolving around the sun, for Uranus is larger than Earth and will have a slight pull of gravity on it slightly shifting it's revolving around the sun.
I don't know ask ya mum :P
