* Order from the Sun: If you're asking about the planet closest to the Sun, then the answer is Mercury.

* Order of Formation: Scientists believe that the inner planets (Mercury, Venus, Earth, Mars) formed first, followed by the outer planets (Jupiter, Saturn, Uranus, Neptune).

* Order of Discovery: We actually discovered Venus first, followed by Mars and Jupiter - but that's just because we've been looking at the sky for a long time!

So, it really depends on your perspective! 😊
