During its continued mission, NASA’s Juno spacecraft will maintain its 53-day polar orbit around Jupiter. At its closest, Juno passes within 3,000 miles (5,000 kilometers) of Jupiter’s cloud tops once during each 53-day orbit. At the high end of each orbit, Juno is about 5 million miles (8-million kilometers) from the planet – which is just beyond the orbit of the Jovian moon Themisto. Credits: NASA/JPL-Caltech

Analysis of asteroids like Lutetia was used in the Josef Hanuš-led paper on asteroid thermophysical modeling. Lutetia is a large main belt asteroid about 62 miles (100 kilometers) in diameter. Lutetia was visited by ESA's Rosetta spacecraft in 2010. Credits: ESA 2010 MPS for OSIRIS Team MPS/UPD/LAM/IAA/RSSD/INTA/UPM/DASP/IDA

This artist’s impression shows the exiled asteroid 2004 EW95, the first carbon-rich asteroid confirmed to exist in the Kuiper Belt and a relic of the primordial Solar System. This curious object likely formed in the asteroid belt between Mars and Jupiter and must have been transported billions of kilometres from its origin to its current home in the Kuiper Belt.
