Orbiting a small object around the sun?

Is it possible to orbit a small object around the sun, lets say a small satellite. If possible how?Orbiting a small object around the sun?
There are man made satellites in solar orbits. For example, the Solar and Heliospheric Observatory (SOHO) satellite:

The way that you put any spacecraft into a circular orbit around any celestial body is pretty much the same. First, you launch the spacecraft into a trajectory that is tangent to the desired circle at some point, and then when the spacecraft reaches that point, you either speed it up, or slow it down (whichever is necessary) so that it will follow the circular trajectory from then on.





The concern expressed by Alwin is that not every possible orbit around the sun is a STABLE orbit. A satellite in an unstable orbit would be influenced by the gravity of the planets, which would cause it to leave the desired circular path.





The SOHO spacecraft sits near the Earth/Sun L1 'lagrangian' point which means that its orbit around the sun is both stable, and synchronous with the orbit of the Earth.

Alexis,





Yes, it's technically true that ';all objects in the solar system orbit the sun,'; but that's not how we usually speak of them. The Earth and the Moon, for example, do a slow dance around one another as they both orbit the sun, but most people would prefer to describe the situation by saying that, ';The Moon orbits the Earth.';Orbiting a small object around the sun?
PRACTICALLY IT IS NOT POSSIBLE AS IF A SATELLITE WANT TO ORBIT AROUND THE SUN IT SHOULD BE FREE FROM OUTER FORCES POWERFUL THAN SUN'S. SO IF IT REACHES NEAR ANY PLANET IT WILL BE ATTRACTED BY THE PLANETS CORE AND HENCE WILL LOOSE THE ORBIT. IF IT SHOULD REVOLVE AROUND THE SUN IT MUST BE NEARER TO THE SUN AND AWAY FROM OTHER PLANETS BUT IF IT REACHES CROSS VENUS DISTANCE FROM THE SUN IT WILL BURN OFF BY THE HEAT OF SUN.
All objects in the Solar System are in orbit around the Sun.





If you mean is it possible for a satellite to orbit the Sun without being gravitationally bound to another object in the Solar System, yes, it is most certainly possible.
Yes.





The Helios satellites were objects that fit your specifications.
