Both are equally appropriate when viewing a truly marvellous photograph taken on the 23rd March by NASA's Mars Reconnaissance Orbiter of one of the planet’s two moons Phobos.
The satellite was named after the Greek God, a son of Ares and Aphrodite. The name was chosen by the moons discoverer, the American astronomer Asaph Hall who also named the second Martian moon Deimos, who was the mythological characters brother.
Phobos itself is only 22 km (13.5 miles) in diameter. Its small size accounts for the irregular shape as its gravitational force is too weak to pull itself in to a sphere.
Enough said, enjoy.
