List of largest rifts and valleys in the Solar System
From Infogalactic: the planetary knowledge core
Lua error in package.lua at line 80: module 'strict' not found. Following are the longest, widest, and deepest rifts and valleys in various worlds of the Solar System.
List
| World | Rift/Valley | Length | Max. width | Max. depth | Notes |
|---|---|---|---|---|---|
| Venus | Baltis Vallis | 6,800 km (4,200 mi) | 3 km (2 mi) | A lava channel | |
| Earth | Atlantic Ocean | ≈10,000 km (6,000 mi) | ≈6,000 km (4,000 mi) | 7.758 km (4.821 mi) | Length taken to be that of the Mid-Atlantic Ridge. (The ridge also has a secondary rift valley running its length.) The width is an average taken along the spreading ridges (Georgia–Senegal, Brazil – Bight of Benin, etc.). The greatest depth is the Romanche Trench. (The Puerto Rico Trench is not part of the rift system.) |
| Great Rift Valley | 6,000 km (3,700 mi) | 220 km (140 mi) | 2 km (1 mi) | Width and depth are those of the Red Sea Rift, discounting continental shelves < 200 m deep. (These may not be the extremes of the whole rift system.) Length of the Red Sea section 2,250 km (1,400 mi). | |
| West Antarctic Rift | |||||
| Keweenawan Rift | 2,000 km (1,200 mi) | 70 km (40 mi) | 0.27 km (0.17 mi) | Width & depth Isle Royale – Keweenaw Peninsula; may not be widest point. | |
| Colca Canyon | 4.160 km (2.58 mi) | ||||
| Cotahuasi Canyon | 3.535 km (2.197 mi) | ||||
| Moon | Vallis Snellius | 592 km (368 mi) | ≈ 30 km (20 mi)? | Width assumed to be approx. that of Vallis Rheita | |
| Mars | Valles Marineris | 3,769 km (2,342 mi) | 200 km (100 mi) | 7 km (4 mi) | |
| Kasei Valles | 1,780 km (1,110 mi) | 200 km (100 mi) | 2–3 km | ||
| Tiu Valles | 1,720 km (1,070 mi) | ||||
| Ares Vallis | 1,700 km (1,100 mi) | ||||
| Vesta | equatorial channels | Possibly up to 1,700 km (1,100 mi) | Length may be as much as the 1790-km circumference of Vesta | ||
| Divalia Fossa | approx. 465 km (290 mi) | ≈ 22 km | Compression fracture from Rheasilvia | ||
| Saturnalia Fossa | at least 365 km (230 mi) | ≈ 39 km | 365 km visible at one point; rest in northern shadow.[1] Compression fracture from Veneneia. |

| Europa | ? | ? | More than 20 km (10 mi) | Moon of Jupiter | |
| Tethys | Ithaca Chasma | 2,000 km (1,000 mi) | 100 km (60 mi) | 3–5 km (2–3 mi) | Moon of Saturn. Ithaca span approx. 75% the circumference of the Moon. |
