No one owns space — the Outer Space Treaty 1967 declared that space is free and open to exploration by all nations and that claims of national sovereignty over outer space or any celestial body are banned.

Most countries, but not all of them, have ratified the treaty.

the same country that in practice owns the seas with the "freedom of navigation".
