With this space list, astro-nuts can vote up the best planets in the solar system to settle once for all a question that has vexed humanity since we first gazed up at the stars: Which planet is the coolest? That's right, astronomy nerds, this is a rankable battle royale to determine the best planet in the solar system. The last planet standing wins the most contested championship title in our neck of the Milky Way!
Ladies and gentlemen, this one's for all the marbles. Which celestial object will be ranked as the most popular and therefore best planet in our stellar neighborhood? Will it be a ringed planet like Saturn? Or could it be Jupiter, that lovable gas giant? How about Mars, the planet right next door? Or maybe it'll be this pale blue dot, the familiar and lovable Earth? Even Uranus stands a chance, since its name gets giggles.
All the planets in the solar system have a shot at becoming the best. Except Pluto. Pluto's not a real planet. No matter how much we wish that plucky little underdog could compete, if we let Pluto play, then a bunch of other dwarf planets and trans-Neptunian objects would get to compete, too, and trust us, you don't want to bring those lightweights into this epic solar system smackdown.Everyone has a planet they just know is the best, whether it has rings, a poisonous atmosphere, or a whole squad of moons as backup. So set aside that telescope and vote up your favorite planets in our solar system!
Home to you, me, everyone we know, and everyone who has ever lived. This place is great. It's got just the right amount of oxygen, sunlight, and all the essential ingredients for life as we know it. It may not be as exciting or mysterious as some of the flashier planets, but Earth's been pretty good to us.
Earth, also called the world and, less frequently, Gaia is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical object known to accommodate life. The earliest life on Earth arose at least 3.5 billion years ago. Earth's biodiversity has expanded continually except when interrupted by mass extinctions. Although scholars estimate that over 99 percent of all species that ever lived on the planet are extinct, Earth is currently home to 10–14 million species of life, including over 7.3 billion humans who depend upon its biosphere and minerals. Earth's human population is divided among about two ...more
A little flair can go a long way, and Saturn has arguably the best most eye-catching piece of flair in the solar system. Its beautiful rings made of ice and carbonaceous dust make it stand out in a line up of the planets, plus it has over 100 moons and moon-nuggets.
Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Named after the Roman god of agriculture, Saturn, its astronomical symbol represents the god's sickle. Saturn is a gas giant with an average radius about nine times that of Earth. While only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive. Saturn's interior is probably composed of a core of iron, nickel and rock, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium and an outer gaseous layer. The planet exhibits a pale yellow hue due to ammonia crystals in its upper ...more
The other other ringed planet, Neptune's on the outer edge of the system, but it's a sharp blue color, thanks to all the methane in the atmosphere. Its orbit may keep Neptune in the backwaters of the solar system, but this icy mix of water, methane, and ammonia has something crucial going for it: mystery. Voyager 2 is the only spacecraft that's ever really paid a visit to Neptune.
Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Among the gaseous planets in the solar system, Neptune is the most dense. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth but not as dense. On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth–Sun distance. Named after the Roman god of the sea, its astronomical symbol is ♆, a stylised version of the god Neptune's trident. Neptune was the first planet found by mathematical prediction rather than by empirical observation. ...more
This place seems pretty cool. A little barren, maybe, but it is our closest neighbor, so we should probably at least have a look around, maybe see if someone left the water running. We've already left a bunch of rovers there, so we might as well go pick 'em up.
Mars is the fourth planet from the Sun and the second smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, largest volcano and second-highest known mountain in the Solar System and the ...more
