There is only one planet in the solar system that does not have a natural satellite or quasi-satellite. That planet is Mercury. When M.E.S.S.E.N.G.E.R, a spacecraft that went to visit Mercury, it detected a red shift but that signal turned out to be a binary star, 31 Crateris.

This includes all the other stars and any planets/comets/asteroids revolving around them.

What are the large objects in space that orbit a star such as the sun?
The answer is planets.
Group of objects in space that move around a central star?
Solar system
How can you tell something is a planet and not a moon?
A planet is in direct orbit around a central star, while a moon is in orbit around a large body (a planet) rather than in a direct orbit around a star. The moon orbits the planet, while the planet orbits the sun.
What is the orbital far point called?
For objects in orbit around the sun, it's the aphelion. For objects in Earth orbit, it's the 'apogee', and in orbit around the moon, it's the 'apolune'.
Which scientist speculated that magnetism hold planets in their orbit?
No scientist speculated it because scientists know that electric and magnetic attraction is polarised, i.e. some objects attract and others repel. Also magnetism does not have poles, so it is impossible to generate a 'central force' which is necessary for an orbit as we know it. On the other hand gravity is a weak force but all objects attract all other objects and it is possible for a massive object to provide a central gravity force to set up orbits.
What is made of a central star around which various other non-star objects orbit?
A solar system.
Does Sedna the planet orbit another star?
Sedna, like all objects in our Solar System orbit the Sun. The Sun and thus everything else, also orbit around the central core of our Galaxy - The Milky Way.
What are the large objects in space that orbit a star such as the sun?
The answer is planets.
A star and all the objects that orbit it are?
A solar system.
Is it true that a star with its orbiting planets is the solar system?
Yes, the solar system consists of a large central star (called the sun for our solar system), with planets that ore in orbit around it. There are other bodies in orbit around the sun also, such as minor planets, asteroids, comets, and other small objects.
Why are moons and planets different?
Planets are bodies that orbit a central star (in our case, the Sun), and moons are smaller bodies that orbit planets.
Group of objects in space that move around a central star?
Solar system
A system in which plants moons asteroids and comets orbit a star?
Natural objects that orbit a star form that star's solar system. The name comes from the name of our star, which is Sol. Earth is part of the Solar System. Another star's system might be referred to by the name of that star, as in the Polaris System.
Is it possible for planets to orbit anything but a sun?
No, because part of the definition of "planet" is that it orbits a sun or star. However, an object the size of a planet can orbit just about anything: a neutron, a black hole, a star cluster, a larger planet, a galaxy, a galaxy cluster... several objects of planetary mass have been found that move freely through space, i.e., that don't orbit a star. Such objects would simply not be called a "planet" because they doesn't orbit a star. In most such cases, they would also be too cold to sustain life as we know it.No, because part of the definition of "planet" is that it orbits a sun or star.

How is a planet different from a moon?
A Planet revolves around a central star (our Sun in the case of our Solar System). A Moon revolves around a planet.
What is the name of the path that a body follows as it revolves around another body?
Revolve can have two meanings. In this instance, the answer is orbit. Revolve can also have the meaning of an object spinning on it's axis. In the solar system, planetary objects spin on their axes as they orbit around the Sun. Most objects smaller than planetary objects probably also have rotational properties along with their orbital motion. Edit: Astronomers use the word "rotation" for axial spin.
What is are planet system-?
its the universe with our planets and moons in it
