Assuming you are talking about an atom, which you really should have stated in your question, the nucleus (the "central part" of the atom) consists of neutrons and protons. The particles orbiting the nucleus are electrons.

An elliptical orbit is a non-circular orbit where the orbiting object follows an elongated path around another object.
The NASA craft currently orbiting Mercury is called the MESSENGER spacecraft. It was launched in 2004 and entered orbit around Mercury in 2011 to study the planet's composition, geology, and magnetic field.
Electrons are the particles that circle the nucleus of an atom.
The small lumps orbiting the sun are called asteroids. They are rocky objects that vary in size and are mostly located in the asteroid belt between Mars and Jupiter.
The central part of an atom is called the nucleus. It contains protons and neutrons, surrounded by orbiting electrons.
To the extent that "other solar systems" are referred to at all, they are referred to by the name of the central star. So if planets were discovered to be orbiting around the star Tau Ceti, it would be called the "Tau Ceti system".
The cloud of negatively charged particles that surround an atom is called the electron cloud. It consists of electrons orbiting the nucleus in various energy levels or orbitals.
The largest satellite orbiting the Earth is the Moon.

The solid particles around which clouds can form are called cloud condensation nuclei (CCN). These particles can be dust, smoke, or sea salt, among others, and they provide a surface for water vapor to condense and form cloud droplets.
Two stars orbiting one another are in a Binary System

The space station currently orbiting Earth is called the International Space Station (ISS). It serves as a research facility for various countries and is inhabited by astronauts from around the world.
