Neptune is far away. People cannot see it with the naked eye. Scientists used math calculations to guess the location of a planet far out in space. Later, in 1846, they confirmed that Neptune was there with the help from a telescope.

Neptune is named after the Roman god of the sea. The planet is a beautiful blue color. It gets this color from a type of gas in its atmosphere. This gas is called methane.
