ununoctium is the heaviest substance...
Ununoctium (i /uːnuːnˈɒktiəm/ oon-oon-OK-tee-əm),[8] also known as eka-radon or element 118, is the temporary IUPAC name[9] for the transactinide element having the atomic number 118 and temporary element symbol Uuo. On the Periodic Table of the elements, it is a p-block element and the last one of the 7th period. Ununoctium is currently the only synthetic member of Group 18. It has the highest atomic number and highest Atomic Mass of all discovered elements.

The heaviest naturally occurring element is uranium92,(U92); its atomic mass is 238.02.
Scientists can prepare heavier elements by bombarding them with neutrons and such. The resulting elements are man made. The heaviest man made element is Ununoctium118(Uuo118). Its atomic mass is 294.

Really, that depends what you are willing to accept as "object". You have stars, star clusters, galaxies, galaxy clusters, galaxy superclusters... and structures like the "great wall", which contain an incredible number of galaxies, and are at least a billion light-years long. And of course there is the Universe itself.

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.
Which is the heaviest planet?
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]
