There's a bit of a misunderstanding in the question! There's no such thing as "two first planets". Here's why:

* Order of Planets: The planets in our solar system are ordered by their distance from the Sun. Mercury is the closest, followed by Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

* "First" is Ambiguous: "First" could refer to the order of discovery, but that's not a strict definition. Historically, we've known about some planets longer than others.

So, what might you be asking?

* "What are the first two planets from the Sun?" This would be Mercury and Venus.

* "What are the first two planets discovered?" This is a little more complicated as early civilizations observed planets without knowing exactly what they were. The answer would likely involve planets visible with the naked eye like Venus, Mars, Jupiter, and Saturn.

Let me know if you have a specific question about planets, and I'll be happy to help!
