Where is the Nix moon?
Pluto
Nix is the inner of the two moons discovered orbiting Pluto in 2005. Nix and Hydra are roughly 5,000 times fainter than Pluto and are about two to three times farther from Pluto than its large moon, Charon, which was discovered in 1978. Nix and Hydra are roughly 20 to 70 miles (32 to 113 km) wide.

What is Nix made of?
using the Hubble Space Telescope’s Advanced Camera for Surveys (ACS), have indicated that it is likely as grey as the remaining satellites. From these observations, it is likely that the surface of Nix is composed primarily of water ice (like Hydra) and may or may also have trace amount of methane ice on its surface.

What is the diameter of Nix?
49.8 km
Nix is a natural satellite of Pluto, with a diameter of 49.8 km across its longest dimension.
How far away is Nix from Earth?
2.6 billion to 4.7 billion miles
Nix is dimmer and thus thought to be slightly smaller than Hydra, but ranging 2.6 billion to 4.7 billion miles (4.2 billion and 7.5 billion km) away from Earth, the moons are too dim and distant for astronomers to be able to tell exactly how small they are.
Does Nix have an atmosphere?
Because Nix has no atmosphere, it isn’t as spectacular as the images looking back at Pluto, but measuring the brightness of that little crescent of light can help tell us about what the surface of Nix is made of, and whether its surface is smooth or covered in boulders.
How long is a day on Nix?
Its orbital period is roughly 24.9 days, meaning it takes about 25 days to complete a single orbit of Pluto. As with Hydra and perhaps the other small Plutonian moons, Nix rotates chaotically, which is due mainly to its oblong shape.
Who discovered Nix and Hydra?
Max J. Mutchler
Since Hydra’s brightness is about 5,000 times fainter than Pluto, long exposure images of Pluto were taken in order to find Hydra. The discovery images were taken on 15 May 2005 and 18 May 2005. Hydra and Nix were independently discovered by Max J. Mutchler on 15 June 2005 and by Andrew J.
Why is Nix and Hydra important?
In making the selection, team members explained that Nix and Hydra honor the search for new satellites and the New Horizons mission to Pluto by starting with the letters “N” and “H.” The first letter of Hydra also honors the Hubble Space Telescope that was used to detect the satellites.
What is Hydra moon made of?
Pluto’s smaller moons, including Hydra, were thought to have formed from debris ejected from a massive collision between Pluto and another Kuiper belt object, similarly to how the Moon is believed to have formed from debris ejected by a large collision of Earth.

How old is Hydra moon?
about four billion years old
Derived from crater counting data from New Horizons, the surface of Hydra is estimated to be about four billion years old.
Is Nix or Hydra bigger?
Hydra is a natural satellite of Pluto, with a diameter of approximately 51 km (32 mi) across its longest dimension. It is the second-largest moon of Pluto, being slightly larger than Nix.
What is the history of Nix the Moon?
Nix was discovered by researchers of the Pluto Companion Search Team, using the Hubble Space Telescope. The New Horizons team had suspected that Pluto and its moon Charon might be accompanied with other moons, hence they used the Hubble Space Telescope to search for faint moons around Pluto in 2005.
What is the Nix moon of Pluto?
Nix is a non-spherical moon of Pluto. It was found along with Hydra in June 2005 by the Hubble Space Telescope Pluto Companion Search Team.
How did New Horizons find Nix and Hydra?
Discovery images of Nix and Hydra. Nix was discovered by researchers of the Pluto Companion Search Team, using the Hubble Space Telescope. The New Horizons team had suspected that Pluto and its moon Charon might be accompanied with other moons, hence they used the Hubble Space Telescope to search for faint moons around Pluto in 2005.
What does Nix stand for?
The formal name “Nix”, from the Greek goddess of darkness and night, and mother of Charon, was announced on June 21, 2006 on IAU Circular 8723, where the designation Pluto II is also given. Together with Hydra, Pluto’s third moon, the initials are those of the New Horizons probe.
