The Earth would appear surrounded by a bright ring, even though the Sun is completely hidden behind it. The ring is sunlight refracted through the atmosphere. It's basically all the sunrises and sunsets, seen at once.

The Earth would never appear fully dark. The bright ring around it will always be there. This is due to the atmosphere.
