If you were to order the planets by size from smallest to largest they would be Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn and Jupiter. Jupiter and Saturn are sometimes called the gas giants, whereas the more distant Uranus and Neptune have been nicknamed the ice giants.
There were nine planets in the solar system, Which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Now we have only eight planets as pluto is excluded.
Because Eris was initially thought to be larger than Pluto, it was described as the "tenth planet" by NASA and in media reports of its discovery.
Kid-Friendly Neptune
It's the last of the planets in our solar system. It's more than 30 times as far from the Sun as Earth is. Neptune is very similar to Uranus. It's made of a thick soup of water, ammonia, and methane over an Earth-sized solid center.
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Saturn has 53 known moons with an additional 29 moons awaiting confirmation of their discovery—that is a total of 82 moons.
This minor planet was named in honor of Carla Ziegler, a friend of the Bohrmann family at Heidelberg. The official naming citation was published by the Minor Planet Center in October 1954 (M.P.C. 1129).
Planet Nine is unnamed, unconfirmed, and unknown. We haven't been able to detect it, and we don't even know for sure that if we did spot it, it would even be a planet. It might be a special kind of black hole, or be made entirely of dark matter.
Venus, the third brightest object after the Sun and Moon, was named after the Roman goddess of love and beauty. It's the only planet named after a female god.
Eden was an uninhabited planet in the Beta Quadrant. This planet was located along the Romulan side of the Neutral Zone.
The atmosphere of the planet Uranus contains mostly hydrogen, helium, and methane. Interestingly, the methane in the atmosphere is what gives Uranus its distinctive blue color. Since Uranus contains effectively zero free oxygen, the hydrogen and methane in the atmosphere does not burn or explode.
Astronomers have announced the discovery of the 100th planet known to inhabit another solar system. The star is 100 light years from Earth in the southern constellation Grus, or The Crane. The planet, one and a half times the mass of Jupiter, has a roughly circular orbit, like those of the sun's family of planets.
No other planet in our solar system has rings as splendid as Saturn's.
Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.
Kid-Friendly Venus
Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. The atmosphere traps heat, making it feel like a furnace on the surface.
Quaoar (pronounced “kwar-waar”) is a dwarf planet about 700 miles/1,110 kilometers in diameter—about half the size of Pluto—that orbits the Sun beyond Neptune in the remote and cold Kuiper belt region.
Here's a good interview question to test their smarts: What is the diamond planet worth? The answer: $26.9 nonillion ($26.9 followed by 30 zeros). Sure, this is the first time in your life that you have ever thought of a nonillion. But you've surely thought of trillions before — and that's a one followed by 12 zeros.
Jupiter is the most massive planet in the Solar System (1000 times than Earth) but nevertheless it is 1000 times less massive than the Sun (play with goo.gl/JpS3WK). Jupiter has ~60 natural satellites (moons) but here we will just mention the four more largest: Io, Europa, Ganymede, and Callisto.
In 2006 the International Astronomical Union (IAU) demoted the much-loved Pluto from its position as the ninth planet from the Sun to one of five “dwarf planets.” The IAU had likely not anticipated the widespread outrage that followed the change in the solar system's lineup.
Venus: Venus has a very dense atmosphere that contains about 97% carbon dioxide, a greenhouse gas that traps the Sun's radiation and heats the planet's surface to a whopping 872°F (467°C). The surface of Venus is the hottest in the solar system! Venus is too hot to have any type of ice on it.
Tough Place for Life
It is unlikely that life as we know it could survive on Mercury due to solar radiation, and extreme temperatures.
In this terminology, since Uranus and Neptune are primarily composed of ices, not gas, they are more commonly called ice giants and distinct from the gas giants.
God is the One who decides who does or does not enter heaven. There's no place in the Bible that says they were saved. But there is no place in the Bible that indicates the couple was lost, either.
