What is the farthest planet from earth?

The title should be "Farthest Planet from Earth".

Farthest Planet from Earth

The definition of "farthest planet from Earth" depends on what you mean by "planet." If we're talking about planets within our own solar system, the answer isn't as straightforward as it used to be.

• Neptune: For a significant period, <a href="https://www.wikiwhat.page/kavramlar/Neptune">Neptune</a> was considered the farthest planet when Pluto was still classified as a planet. Its distance from Earth varies due to the elliptical orbits of both planets, but it's generally several billion kilometers away.

• Pluto: Once considered the ninth planet, <a href="https://www.wikiwhat.page/kavramlar/Pluto">Pluto</a> is now classified as a dwarf planet. Because of its eccentric orbit, Pluto's distance from Earth varies greatly, and at times it is actually closer to the Sun than Neptune. At its farthest, it's over 7.5 billion kilometers from Earth.

• Hypothetical Planet Nine: There is ongoing research and speculation about the possibility of a <a href="https://www.wikiwhat.page/kavramlar/Planet%20Nine">Planet Nine</a> in the distant outer solar system. If it exists, it would be significantly farther than even Pluto, but its existence has not yet been confirmed.

• Exoplanets: When considering planets outside our solar system (exoplanets), the concept of "farthest" becomes immense. The distances to <a href="https://www.wikiwhat.page/kavramlar/Exoplanets">Exoplanets</a> are measured in light-years. There are countless exoplanets at vastly different distances, with some of the most distant ones being many billions of light-years away. The observable universe is constantly expanding, and with it the number of observed and estimated planets.
