NASA’s report of 2019 claimed that Mercury is the nearest to the Earth.
The nearest planet to the Earth is Mercury. For a long time, Venus was thought to be the closest planet to Earth. However, Venus is only the nearest planet when it falls between the Earth and the Sun during its course of revolution.
