Here's why:

* Distance: While Earth might look small from other planets, it's still visible with the right telescopes.

* Reflecting Sunlight: Earth reflects sunlight, making it a bright object in space.

However, the view of Earth from different planets varies greatly:

* Mercury and Venus: Earth appears as a very bright star.

* Mars: Earth would be visible as a bright point of light, but only with a powerful telescope.

* Outer Planets (Jupiter, Saturn, Uranus, Neptune): Earth would be a faint dot, visible only with the most advanced telescopes.

It's important to note that seeing Earth is very different from seeing it in detail. The images we have of Earth from other planets are taken by powerful space probes, not by human eyes.
