Neptune, the eighth and most distant planet from the Sun in our solar system, holds the title of being the farthest.
Known for its striking blue hue, Neptune is an ice giant composed primarily of hydrogen and helium, with traces of methane contributing to its distinctive color.1 Its orbit is notably eccentric, meaning its distance from the Sun varies significantly throughout its 165-year journey around the Sun. At its farthest point, Neptune is approximately 2.8 billion miles away from the Sun, making it a truly distant world.
