The cache IS NOT at the posted coordinates.
This cache is Part of the Caches Across the Solar System series in Southern California, which will take visitors to scale representations of the Planets, Dwarf Planets, Moons, and Other Objects of the Solar System, with the Great Park Balloon representing the Sun. Find at least 9 CASS Caches across the 3 zones, stamp your passport, and turn it in at the Signal's Island Block Party (GCAXN0B) for prizes!
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth and a tenth that of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital period of 11.86 years. It is the third-brightest natural object in the Earth's night sky, after the Moon and Venus, and has been observed since prehistoric times. Its name derives from that of Jupiter, the chief deity of ancient Roman religion.

The posted coordinates will bring you to the scale "model" of Jupiter in regards to the rest of this Solar System. However, you will not find the cache there. Instead, directly adjacent to the model, you will find a sign in the shape of a leaf. Enter the word found on the third line of text on this sign into certitude to obtain the final coordinates.
