Q&A for How to Remember the Order of the Planets in Our Solar System

A popular way to remember them is 'My Very Easy Method Just Sums Up Naming Planets'. Note that Pluto is included in this, but it's not a true planet.

It is different for each planet, depending on how close it is to the sun. It takes 1 Earth year for Earth revolve, but only 88 Earth days for Mercury. It takes Pluto 248 years to orbit.

The ninth planet used to be Pluto before it was demoted to a dwarf planet. There is also a Planet Nine, which is a hypothetical planet in the outer Solar System. Its gravitational influence could explain the abnormal orbits of a group of trans-Neptunian objects found mostly beyond the Kuiper belt.

In 2001 a bunch of astronomers got together and formally defined the term planet. A planet must meet 3 criteria now, and Pluto only meets 2. A planet must be in orbit around the sun (check), must be large enough to have assumed a spherical shape due to gravity (check), and must have cleared its orbit of other floating objects (fail).

Astronomy has come so far in the last decades, and scientists now have more information that led them to the conclusion that Pluto should be reclassified. Pluto isn't sentient; it doesn't mind its new dwarf planet status.

My very eager mother just served us nine pizzas -- the planets, in order, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.

Not in our solar system, but scientists are constantly discovering new planets in the far reaches of space.

The planets in that order would be Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter. To remember that, you could write a story to help yourself. For example, you could say that Pluto was skating and hit Mercury, who was eating a Mars chocolate bar. The chocolate bar hit Venus, who was just proposing to Earth. Venus was angry, and she attacked Neptune and Uranus, who were only children at the time. They cried for their parents, Saturn and Jupiter, who chased Venus away. You could make up any story you'd like though!

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. They're named in order under Method 4 Step 2.

Neptune takes the longest amount of time to orbit the sun.

Whatever mnemonic device helps you remember them is the best.

Pluto was very small in size and did not have the qualities to be a planet.

So my very easy method just speeds up naming planets = Sun Mars Venus Mercury Jupiter Saturn Uranus Neptune Pluto.

The sun has a diameter of 1.391 million km. By comparison, the earth is only 13,000 km in diameter.

There are only three. They are Pluto, Eris, and Ceres. Maybe try and remember "PEC," or come up with a short sentence or phrase that uses those three letters.

Mercury is the planet nearest the Sun. Venus is usually called the Morning Star or Evening Star, but those nicknames are sometimes applied to Mercury. Jupiter is the largest planet in our solar system.

That is the subject of disagreement among astronomers. In 2006 the International Astronomical Union re-designated Pluto a "dwarf planet" instead of a "planet" because of its small size relative to other planets in our solar system, of which there are now eight.

The International Astronomical Union (IAU) prefers the term "small Solar System object." For many years Sedna was known as a "minor planet" (more or less the same as a "dwarf planet") and is also referred to as a "trans-Neptunian object."

There is only one star in our solar system: our Sun. But, there are billions of stars in our Milky Way galaxy that make up shapes that we call 'Constellations' like Orion (the Hunter), Cassiopeia (the Queen), Taurus (the Bull), Ursa Major (the Big Bear), etc. There are also shapes of stars that we recognize, that we call 'Asterisms' like the Big Dipper (part of Ursa Major), the Summer Triangle (Vega, Deneb, and Altair), and many others.

There are 8 planets in our solar system. They are divided into two groups the inner and outer planets. The first planet is Mercury named after the Roman messenger god which is closest to the sun, Venus named after the Roman god of beauty nicknamed Earth’s twin because of similar size and mass of our planet, Earth which is the only planet that supports life and Mars named after the Roman god of war, nicknamed the red planet. After Mars, the asteroid belt borders the inner and outer planets. Jupiter named after the Roman king of the gods is the largest planet, Saturn named after the Roman god of agriculture, known for having large rings, Uranus named after the Roman god of the sky, and Neptune.

No, it was reclassified a dwarf planet because: a) An object larger than Pluto (Eris) was found in the asteroid belt and many others of a similar size. If Pluto was a planet so would all of these other objects be one. It was decided that this would be too many planets, for whatever reason. b) Its orbit is irregular as it crosses Neptune's. c) Unlike the other planets, it has not cleared the area around its orbit of debris.

In the solar system, there are 8 planets — Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The exact number of dwarf planets is not yet known. As of 2019, the following are accepted as dwarf planets by the IAU: Pluto, Eris, Haumea, Makemake and Ceres. Other research suggests that there are 9 dwarf planets in the solar system. However, some estimates go as high as 50. Outside the solar system there are many more planets, which are called exoplanets. As of 1 September 2019, there are 4109 confirmed exoplanets.

No. The sun is a star, while the moon is a natural satellite that orbits the Earth.

Mercury. It is about 3,031.9 miles across. For reference, the moon is 2,158.8 miles across.

Gravity keeps them in an elliptical orbit around the sun. As you get closer to the sun, it takes a shorter amount of time to orbit.
