[15] It is tied with three other asteroids as the thirteenth largest asteroid, and it is one of the two largest stony asteroids, along with 15 Eunomia.

Mar 12, 2025 · After enduring a five-year, 1.7 billion-mile journey from Earth, and evading showers of the most punishing radiation outside the Sun, Juno has provided breathtaking images and breakthrough discoveries from Jupiter and its moons.

Juno is a NASA space probe orbiting the planet Jupiter. It was built by Lockheed Martin and is operated by NASA 's Jet Propulsion Laboratory.

The Juno spacecraft, which entered orbit around Jupiter on July 4, 2016, is the first explorer to peer below the planet's dense clouds to answer questions about the gas giant itself and the origins of our solar system.

Juno is the first space mission to orbit an outer-planet from pole to pole, the first to fly as close as 2,600 miles to Jupiter’s cloud tops, and the first mission to be designed to operate in the heart of Jupiter’s radiation belts.

With its suite of science instruments, Juno will investigate the existence of a possible solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras.
