The Biggest Exoplanets vs Sun vs Jupiter: Size Comparison (2024)

Exoplanets, or planets that exist outside of our solar system, come in a wide range of sizes. Some exoplanets are so large that they rival the size of our own sun or Jupiter, the largest planet in our solar system. Let’s take a look at some of the biggest exoplanets discovered so far and compare their sizes to the sun and Jupiter.

1. WASP-17b

WASP-17b is one of the largest exoplanets discovered to date. It has a radius about 1.5 times that of Jupiter, making it one of the largest exoplanets known to astronomers. However, compared to the size of the sun, WASP-17b is still relatively small.

2. HD 100546 b

HD 100546 b is another massive exoplanet that is larger than Jupiter. It has a radius about 3 times that of Jupiter, making it one of the largest exoplanets known to astronomers. Like WASP-17b, HD 100546 b is still much smaller than the sun.

3. TrES-4b

TrES-4b is a giant exoplanet with a radius about 1.7 times that of Jupiter. While it is smaller than HD 100546 b, TrES-4b is still a very large exoplanet compared to Jupiter. However, like the other exoplanets mentioned, TrES-4b is dwarfed by the size of the sun.

Overall, these exoplanets are some of the largest ever discovered, but they are still much smaller than our own sun. Jupiter, the largest planet in our solar system, is also much smaller than the sun. These size comparisons give us a sense of the vast scale of the universe and the variety of planets that exist beyond our solar system.
