The largest canyon in the solar system is Valles Marineris, located on Mars. This massive canyon is over 4,000 kilometers long, up to 200 kilometers wide, and up to 7 kilometers deep, making it over 10 times longer, 5 times wider, and 5 times deeper than the Grand Canyon in the United States.

Valles Marineris was formed over 3 billion years ago due to tectonic activity and the collapse of the Martian crust. The canyon has been explored by multiple spacecraft, including the Mars Reconnaissance Orbiter and the Mars Express, providing valuable insight into the planet's geological history.

While Valles Marineris is the largest canyon in the solar system, it is not the only one. Other canyons in the solar system include Ithaca Chasma on Saturn's moon Tethys, and Ophir Chasma and Candor Chasma on Mars.
