The Eight Planets in Order From the Sun

with Nova

Nova floats beside a glowing scale model of the solar system suspended in a dark starfield, pointing excitedly at tiny planet spheres arranged in a curving line stretching away from a blazing golden Sun, each planet a different color and size.

Name all eight planets in order from the Sun without a reference card.
Explain why planets closer to the Sun take less time to complete one orbit.
Compare the four rocky inner planets to the four gas-and-ice outer planets.
Identify each planet's position using the memory phrase 'My Very Excellent Mother Just Served Us Nachos.'
Predict which planet a friend is describing based on clues about its distance and neighbors.

Key terms

Orbit: The path a planet takes around the Sun.
Inner planets: The four small rocky planets near the Sun.
Outer planets: The four big planets far from the Sun.
Memory phrase: A silly sentence that helps you remember.

Eight Planets In Order

The Sun sits in the middle, and eight planets travel around it. In order from the Sun, they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest, and Neptune is farthest away. Earth is the third planet, which is our home. The order of the planets always stays the same.

A Trick To Remember

You can remember the order with a silly sentence: My Very Excellent Mother Just Served Us Nachos. Each first letter matches a planet, going M, V, E, M, J, S, U, N. The four planets closest to the Sun are small and rocky. The four farthest away are huge and made mostly of gas or ice.

Worked examples

Which planet is the third one from the Sun?

Count out from the Sun: Mercury, Venus, then the next one.
The third planet is where we live.

Answer: Earth is the third planet from the Sun.

Hey explorer, it's Nova! Ready for the greatest road trip in the solar system? Our Sun sits at the center, and eight planets travel around it in oval-shaped paths called orbits. The closer a planet is to the Sun, the shorter its orbit path AND the faster it travels — so it finishes one loop in much less time. The farther away, the longer the path and the slower the speed, which means it takes much more time. Here are the eight planets in order, starting closest to the Sun: 1. Mercury — tiny and rocky, closest to the Sun, very hot days and freezing nights. 2. Venus — bright and super hot, covered in thick clouds. 3. Earth — that's home! The only planet we know has liquid water and life. 4. Mars — the red planet, with the tallest volcano in the solar system. 5. Jupiter — the giant! So big that more than 1,300 Earths could fit inside it — the largest planet by far. 6. Saturn — famous for its beautiful rings made of ice and rock. 7. Uranus — an ice giant that spins on its side like a rolling ball. 8. Neptune — the windiest planet and farthest from the Sun. A trick to remember the order: My Very Excellent Mother Just Served Us Nachos. Each first letter matches a planet — M, V, E, M, J, S, U, N. The first four (Mercury through Mars) are small and rocky. The last four (Jupiter through Neptune) are huge and made mostly of gas or ice. That dividing line between Mars and Jupiter is called the asteroid belt — a ring of rocky chunks orbiting the Sun. No matter where Earth is in its orbit, the planet order never changes. The planets stay in their lanes!

Activity

Drag each planet card into the correct position from the Sun, then check your order.

Practice

Name the eight planets in order from the Sun.

Tell which planet is farthest away from the Sun.

Common mistakes to avoid

The planet order can changeThe planets stay in their lanes, so the order never changes.

Check your understanding

Which planet is the FOURTH from the Sun?

A student says, 'Saturn must be warmer than Jupiter because Saturn has rings and rings need heat to form.' What is wrong with this idea?

Using the memory phrase 'My Very Excellent Mother Just Served Us Nachos,' what planet does the letter J stand for?

Recap

Eight planets orbit the Sun in order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The closer ones are small and rocky.
