In astronomy, heavy, heaviest etc. is never used as that is a terminology for weight.
Weight is a function of an objects mass and the amount of gravity.
This is why you would weight 120lb on Earth but only 20lb on the Moon.
We therefore use the terminology "mass" as it does not have to take gravity into account.
So the most massive planet is Jupiter have more mass than any of the other planets. [See related question]

What planet is the heaviest?
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.
What is the second heaviest planet?
Comparison of the size of Uranus and the Earth. Uranus is 51118 km or about four Earths wide. It is the third widest and fourth heaviest planet in the Solar System
On what planet would you be the heaviest?
The weight depends upon the mass of the planet. A larger planet has a larger gravitational 'pull', hence Jupiter, being of a great mass objects will weigh the heaviest. To calculate your weight on other planets go to the website below, under 'Related links'.
Which planet has the biggest mountain?
Mars. Its name is Olympus Mons and its heaviest than Mount Everest.
Is Mercury the heaviest planet?
Mars is the heaviest planet. Mercury is the third heaviest. Mars has an iron core that's the same as Earths except that Mars has a greater consistent Iron layout. Mercury is made primarily of iron and has a very low gravity due to its lack of size.

No. In our solar system it is the second most massive planet. Fifth place goes to Earth.
Is the largest planet is the heaviest?
In our solar system, the largest planet, Jupiter, is indeed also the heaviest, weighing in at about 317 times the mass of Earth. However, a larger planet isn't necessarily a heavier one - for example, Uranus is larger but less massive than Neptune.
