This is a 3D animation in which the sun, the earth, and the moon rotate. -You can change the rotation speed. The fastest is 1 second, and the slowest is 300 seconds to make one revolution. -It can rotate in the reverse direction, which is not possible in the natural world. -The earth and the moon can change the light from the sun by 30 degrees. -There are three types of earth: night lights, nature, and globes.

Verdict
The clearest difference is price: 3D Solar System at Free against Earth Rotation's $0.99. 3D Solar System also leads on update cadence (fortnightly vs every 22 months) and ratings volume (1.7K vs 1). Earth Rotation's advantage is rating (5.0 vs 4.4) and in-app purchases (none vs 12). On device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
3D Solar System is free to download; Earth Rotation costs $0.99 up front. 3D Solar System sells 12 in-app purchases, starting at $7.99 per 7 days. Earth Rotation asks for nothing beyond the download.
Earth Rotation holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 1, so its average is the more settled of the two.
3D Solar System ships an update fortnightly, Earth Rotation every 22 months. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
