The Grand Canyon the largest canyon in the world well our world 🌎

Now here's one picture from orbit

But the Grand Canyon is not the largest Canyon we've ever discovered the largest canyon ever discovered is closer than you then well close in  galactic terms but the largest canyon ever discovered is this one

Found on mars it's 4000 kms long (2500 miles) and 7 kms deep (4 miles) compared to the Grand Canyon in Arizona which is only 800 kms long (500 miles) and 1.6 kms deep (1 mile) it is so much bigger than ours yet mars is smaller than earth it makes you think and wonder how is this possible
