The IAU is the global huge organisation that combines more than 10 000 expert astronomers from nearly 100 nations. Its objective is to promote and protect the science of astronomy in all its elements through global cooperation. The IAU likewise functions as the globally identified authority for appointing classifications to heavenly bodies and the surface area includes on them. Established in 1919, the IAU is the world’s biggest expert body for astronomers.

The New Horizons spacecraft is presently 6.16 billion kilometres from Earth, speeding towards a Brand-new Year’s Day 2019 encounter with the Kuiper Belt item (486958) 2014 MU69, which orbits about 1.6 billion kilometres beyond Pluto. This flyby will be the centrepiece of New Horizons’ prolonged objective through the Kuiper Belt, and will be the farthest planetary encounter– with the most primitive item ever experienced– in spaceflight history.
