The Earth is the densest planet. Saturn is the least dense planet; it would float on water

Astronomers have always considered that Earth is the most dense planet in our Solar system. Although there have been no chemical measurements of relative density of all the planets so far, it has been only recently debated that Mercury is the densest planet in our solar system. Mercury is the innermost planet and probably consists mostly of iron. It orbits the sun in 87.969 days and revolves about its axis in two - thirds of the orbital period, 58.646 days.

Terrestrial planet simply refers to any planet that is composed of rock and heavier elements, whereas the other planets, gas giants, are composed of gas and dust, as well as much lighter elements than those found on earth. The terrestrial planets in our solar system were Mercury, Venus, Earth, Mars, and Pluto. Seeing as Pluto is no longer a planet it could not possibly be a terrestrial planet. Though terrestrial planets are much denser, they are also far smaller, and so have smaller masses than the gas giants. Mercury is very small and hot, though it's atmosphere was almost completely destroyed by the intense solar wind at its proximity to the sun, as well as its small gravitational field and weak magnetic field (about 1% of earth's) as a result, mercury is both incredibly hot and incredibly cold, as it retains no heat. Venus is basically Earth if Global warming was about a million times stronger. The atmosphere is mostly carbon dioxide, and sulfuric acid is the standard rain. The atmosphere is also so thick that it's nearly impossible to get a decent picture of the surface. In fact this was only accomplished quite recently, and never directly. Earth is Earth. You are very glad that you live here rather than on any of the other planets. Water has been discovered on other planets, but at far as we can tell Earth is the only planet that maintains perfect conditions for life. Right distance from the sun, right amount of atmosphere, and old enough for minute chemical reactions to take place and form life. I suggest reading up on Iron-Sulfide World theory if you want to know more about that though. Long story short: it is becoming more and more likely that life originated on rocks. Rocks very similar in composition to Fool's Gold actually. It's quite fascinating if you ask me. We have one moon, called either Luna, or just the moon. Mars is a tiny planet much further out from the sun than us. It's really cold, and it looks like basic life may have evolved on mars, but if it exists it's probably just a few strange amoeba's and Tardigrades. If you haven't heard of those either then I suggest you look them up. Basically unkillable, and called water bears. Mars has two moons: Phobos and Deimos. In Greek mythology these were the sons of Mars and their names roughly translated mean Fear and Dread respectively. The moons are very tiny, but so is mars, so it all works out. Mars also has the largest mountain in the solar system: Olympus Mons. It is made of the same substances as our ocean floors, and our big Hawaiian volcanoes. It's a rock called basalt and its composed of mostly magnesium and iron. Pluto is a really really small ice ball rocketing around our outer solar system and it actually has three moons, but for the largest time we could only find one. Charon, Nix, and Hydra. As far as mythology goes, Pluto ruled the underworld; Charon brought dead people over to the underworld; Nix was the mother of Charon; Hydra kept out anyone that Pluto didn't want around. I'm not sure how relevant all of that was, but if you're asking this for personal reasons as opposed to a school assignment I think you'd appreciate it. If not, then the people here can get a quick astro/mythology lesson.

The earth is the densest planet. I was surprised. I thought Mercury was.

Earth is the most dense because of it's Iron core. Lots of the inhabitants on it are dense as well.

I don't think we know for certain; most believe it's Earth, others say Jupiter, still others say Mercury.
