Eris has one satellite
As of now, no robots or satellites have explored Eris directly. Eris, a dwarf planet located in the Kuiper Belt, has only been observed from afar using telescopes. The most detailed observations of Eris were made by the Hubble Space Telescope and other ground-based observatories, but there are currently no missions planned to visit or study Eris up close.
Betelgeuse is a star, not a planet, so it does not have any satellites. Satellites, also known as moons, typically orbit planets, not stars.
have any robots or satellites ever landed on pluto
No, the sun does not have any natural satellites. Natural satellites typically orbit planets, and the sun is a star at the center of our solar system, so it does not have any objects orbiting around it in the same way planets do.
No natural satellites of the planets Mercury or Venus have ever been discovered.
Yes, Eris, a dwarf planet in our solar system, does not have any natural satellites. It is one of the largest known dwarf planets and is located in the outer regions of the solar system beyond Neptune.
Eris doesn't have any rings.
Yes. Eris orbits the sun.
There are 168 known natural satellites (moons) of the 8 major planets. There are also moons around 3 of the 5 dwarf planets (Pluto, Eris, and Haumea). There are more than 200 artificial satellites (or expired satellites) in Earth orbit or scattered throughout the solar system.
no but Eris isn't a planet it is a dwarf planet.
no man could not live on Eris is too cold for any form of life.
Mercury & Venus have no natural satellites.
Probably. Eris is too far away for us to make out and of the features on its surface and we have not sent any probes there.
It is highly unlikely. Eris is too cold to support any conceivable form of life.
Mercury has no satellites.
Venus is one of the few planets that doesn't have any satellites orbiting around it. Venus also is a planet with no moons.
Mercury and Venus do not have any natural satellites.
