Planets in Order from the Sun
Learn the eight planets in order from the Sun—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune—with a simple memory aid and an interactive 3D view.
From the Sun outward, the eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Vastonaut lets you select these worlds in an interactive 3D scene, compare their positions, and open short object information panels.
The eight planets, from the Sun outward
1. Mercury
The smallest planet and the closest planet to the Sun. Its surface is heavily cratered.
2. Venus
A rocky planet with a dense atmosphere and extreme surface temperatures.
3. Earth
Our home world, with stable surface liquid water and the only life known to science so far.
4. Mars
A cold, rocky world known for its reddish surface and evidence of ancient water activity.
5. Jupiter
The largest planet, a gas giant with a deep atmosphere and a large family of moons.
6. Saturn
A gas giant recognized for its broad and bright ring system.
7. Uranus
An ice giant that rotates with an extreme axial tilt compared with most planets.
8. Neptune
The outermost of the eight recognized planets, an ice giant with fast winds.
A memory aid for the planet order
Remember the initials M V E M J S U N with the phrase “My Very Educated Mother Just Served Us Noodles.” The important step is to say the planet names in order while pointing to each destination in the 3D model.
Where do Pluto and Ceres fit?
Pluto and Ceres are dwarf planets, not part of the eight-planet sequence. Ceres lies in the main asteroid belt between Mars and Jupiter. Pluto is a distant world in the Kuiper Belt region beyond Neptune. Vastonaut includes both as destinations, making them useful examples when discussing the difference between planets and dwarf planets.
Try a quick 3D learning activity
- Open Vastonaut and select Overview.
- Find the inner planets—Mercury, Venus, Earth, and Mars.
- Move outward to Jupiter and Saturn, then Uranus and Neptune.
- Ask which planets are rocky and which are giant planets, and explain the clue used to group them.
- Select Ceres or Pluto and discuss why they are categorized as dwarf planets.
For authoritative descriptions, consult NASA's planet guide and NASA's Solar System facts. Vastonaut compresses sizes and distances for navigation, so use scientific references rather than the scene to measure real scale.
