New Horizons

Altitude: -44.8°   Azimuth: 62.7°   Direction: East-North-East

New Horizons is a NASA space probe launched in January 2006 with the mission to explore the dwarf planet Pluto and the Kuiper Belt, the outermost region of the Solar System beyond the orbit of Neptune. The spacecraft completed its flyby of Pluto in July 2015, providing detailed images and data of the dwarf planet's surface, atmosphere, and moons. It then continued its journey into the Kuiper Belt, where it conducted a flyby of the Kuiper Belt Object (KBO) 2014 MU69, nicknamed "Ultima Thule," in January 2019, becoming the first spacecraft to visit a KBO. The New Horizons mission has provided valuable insights into the formation and evolution of the outer Solar System and expanded our knowledge of the icy bodies that reside there.

New Horizons is currently in the constellation of Sagittarius.

The current Right Ascension of New Horizons is 19h 13m 36s and the Declination is -20° 23’ 04” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt).

Visualization of New Horizons Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of New Horizons with respect of the Sun and the orbits of the major planets. The position of New Horizons and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
