* Planets' orbits are elliptical: Planets don't orbit the sun in perfect circles. They have elliptical orbits, meaning their distance from the sun varies.
* Distances constantly change: A planet's distance from the sun changes constantly as it moves along its elliptical path.
However, we can get an idea of which planet might be in that range:
* Jupiter's average distance from the sun: About 778 million km.
* Saturn's average distance from the sun: About 1.4 billion km.
Since 3000 million km falls between these two distances, it's likely that the planet you're looking for is either Jupiter or Saturn. To determine the exact position of either planet at any given time, you would need to consult astronomical data.
