You most likely know about the mnemonic “My very Educated Mother simply Served united state Noodles.”

Indeed, it’s what many students learn about when examining the street of the planets from the sunlight i.e. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and also Neptune.

You are watching: Rank the five terrestrial worlds in order of size from smallest to largest:

While this is more than likely public knowledge, very couple of people room actually conscious of the size of the planets in order. Sure, friend may have heard a thing or two about the second smallest world in ours solar device –Mars- indigenous a pair of sci-fi movies. But, carry out you yes, really know exactly how it compares to the rest of the other planets out there?

Well, our guess is you probably don’t. If you’ve ever wondered around the actual size of the planets in order, then, it’s your lucky day. Here’s exactly how they rank follow to size.

A Mnemonic because that the size of the Planets in Order

Before we acquire started through the countdown, it’s just honorable that we share a mnemonic because that the dimension of the planets in order having already done the same for the street of the planets from the Sun.

It’s a genuine easy one too. To ensure that the list remains stuck, just think the something along the lines of “Mercury Met Venus Every Night till Saturn Jumped.” Essentially, this shows that the dimension of the planets in order from smallest to largest is Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and also Jupiter.

Pretty cool right?

A substantial Review the the size of the Planets in Order

1. Mercury

Other 보다 being the smallest planet in the solar system, Mercury is interestingly smaller sized than earth Moon and extremely hot with temperatures registered going together high together 850 Fahrenheit (454.444 Celsius).

In a bid to learn much more about the planet, NASA deployed the MESSENGER probe method back in 2004. Today, we’ve ascertained the its orbit time is indistinguishable to 88 planet days and that a solitary day top top the world lasts around 59 planet days.

To really acquire a gist that its diminutive size, the diameter is a little bit over 3,000 miles (4828.032 kilometers).

2. Mars

The red-planet is the second smallest planet in the solar system. It’s also regarded together the critical terrestrial planet and also potentially has the capacity to support human being life when the right technology is in place. Given this background, the understandable why SpaceX and also NASA have actually accorded the planet so lot attention in current years.

While this is still a far-off dream, the planet is at this time inhabited through robots who space continually digging up an ext intel top top Mars. In ~ present, we know that the gravity on Mars is a 3rd of what’s uncovered on Earth and that a single Martian work (called a sol), is actually indistinguishable to 25 hours.

3. Venus


Named ~ the roman inn goddess that love, Venus is remarkably much hotter than Mercury and also filled to the brim v greenhouse gases

The planet has actually an mean diameter that 7,500 mile (12,070.08 kilometers) and its orbit takes about 225 earth days come complete. V regards to the length of the day, let’s simply say that you shouldn’t hold your breath for the day to end since the planet has actually a day span equivalent to 241 planet days.

4. Earth

It’s our home planet and also the only one known to maintain and support life. Having been created some 4 billion years ago, the earth has radically changed with the passing of time. Thanks to the tilting nature of its axis, earth experiences 4 seasons and the only natural satellite, the Moon is responsible for the s tides.

With an virtually 8,000 mile (12874.75 kilometers) diameter, the earth takes 365 days come orbit the Sun, and also an planet day large 24 hours.

5. Neptune

As the 8th earth from the Sun, Neptune is the really last that the gas giants. Constitutionally wise, it’s primarily comprised of helium and also hydrogen.


While it’s a known truth that the blue color emanates from an abundance of methane, it continues to be unclear whether Neptune’s main point is solid

With a diameter the 30,755 mile (49,495.375 kilometers), because that Neptune to orbit the Sun, the takes about 165 planet years and also a solitary day ~ above the world is identical to 19 hrs on Earth.

6. Uranus

It’s the third of the gas giants and despite having been discovered in the 1780s, us only controlled to catch the very first glimpse of the earth in 1986 as the Voyager probe was making that rounds.

Scientists believe that the main point of Uranus is actually extremely icy which renders it unique since most various other planets are presumed to it is in molten.

With a diameter that 31,760 miles, Uranus take away an equivalent of 84 earth years to orbit the Sun and also a single day top top the earth translates to 18 earth years.

7. Saturn

This world doubles up as the second largest planet and is additionally the second gas giant. Many recognizable by its one-of-a-kind rings which occurred thanks come the action of ice cream and an are debris.

While the planet is largely made up of helium and also hydrogen, it remains to be uncovered whether Saturn has actually a solid core or not.

The planet has actually a large diameter spanning 75,000 miles (120,700.8 kilometers) and takes around 30 planet years to orbit the Sun. If she looking to invest a work on Saturn, then, you’d have to wait an equivalent of 11 planet hours for a day to pass.

8. Jupiter


As the very very first of the gas giants, Jupiter is the biggest planet in our solar system

Constitutionally speaking Jupiter is composed of helium and hydrogen and also just prefer Saturn, it stays to be watched whether the core is consisted of of solid matter or not.

With a diameter that 86,881 mile (139,821.42 kilometers), the planet is so huge that if it were 80 time larger, it would qualify to it is in a star. To orbit the sun, Jupiter takes around 12 earth years and also a solitary day on the planet is identical to 9 planet hours.

There you have actually it, a comprehensive review that the size of the planets in order. Having highlighted the various attributes of the planets, we’re confident you’re invited with enough knowledge to teach one elementary course a thing or two around the heavens.

If you’re no that confident, you can stock increase on your understanding of the cosmos by having a look in ~ our fantastically do augmented fact 3D design of the Solar System in every its glory.
