The two planets that orbit the Sun faster than Earth are Mercury and Venus.

Here's why:

* Orbital Speed: A planet's orbital speed is determined by its distance from the Sun. The closer a planet is to the Sun, the stronger the gravitational pull and the faster it needs to move to stay in orbit.

* Mercury: Being the closest planet to the Sun, it has the fastest orbital speed.

* Venus: While farther than Mercury, Venus is still closer to the Sun than Earth, resulting in a faster orbital speed.
