Neither Sirius A nor Sirius B have any known planets.
No it does not have any effect on the planet. For Example: Pluto is very far away from the sun. It doesn't have that much mass.
We don't know because it is too far away to see clearly.
Currently, there are only eight planets in our solar system, so there is no tenth planet. The tenth planet ever to be discovered (not counting Pluto as a planet) is a planet that orbits the star PSR B1257+12. It is about a thousand light years away from the sun.
As far as we can actually PROVE, it is the only dwarf planet that orbits our own Sun. However, there has long been some speculation that there may be another dwarf planet out beyond Pluto, that is even smaller, but which is too far away from the Sun to be seen with optical instruments. It has also been debated that some large meteorites that orbit the Sun between the orbits of the planets, should maybe be declared as being dwarf planets in their own right.
It is not clear that Pluto has been pushed anywhere, it is a large Kuiper belt object with an orbit that is not in the plane of the other the Solar System's planet orbits which indicates it is orbiting where it always did. It is Uranus and Neptune that have moved out in their orbits.
no their is no planet which is very far away from the sun but in the past pluto was very far and small thats why it had not been counted as a planet
It various
No. The planets in the Solar System all have almost circular orbits, but the orbits of comets are highly eccentric (oval-shaped). This means that while the distance a planet is from the Sun is rather constant, the path of a comet means it comes close to the Sun, and then moves far away.
How far away is Pluto from all the pther planets?
There is insufficient information provided for a meaningful answer. What is the mass of each moon? How far are each of them away from the planet? What speed are they travelling? What are their orbits, particularly in relation to each other?
Pluto is a dwarf planet.
There is no planet astronomers here on Earth call "nester". So if there is one it is very far away (in space and time)
