What is the farthest planet from earth?

The farthest planet from Earth constantly changes, depending on the positions of the planets in their orbits. There's no single "always farthest" planet. However, if we're talking about the planet that is generally furthest from the Earth on average, that would be Neptune.

Here's some information about Neptune:

• Distance from the Sun: Neptune orbits the Sun at an average distance of about 2.8 billion miles (4.5 billion kilometers). This is about 30 times farther than Earth's distance from the Sun.

• Orbital Period: Because of its greater distance from the Sun, Neptune takes a very long time to orbit the Sun. One Neptunian year is equivalent to about 165 Earth years.

• Size and Composition: Neptune is an ice giant, meaning it's composed primarily of "ices" (water, methane, and ammonia) along with rock and metallic hydrogen. It's the fourth-largest planet by diameter in our solar system.

• Atmosphere: Neptune has a very active atmosphere with strong winds and large storms. Its distinctive blue color comes from methane in its atmosphere.

• Moons and Rings: Neptune has 14 known moons, the largest of which is Triton. It also possesses a faint ring system.

It's important to remember that the relative distances between planets are constantly shifting. While Neptune is generally farthest, at certain points in their orbits, other outer planets like Uranus or Pluto (though no longer considered a planet) might be further away from Earth at a specific moment in time.
