False. No planet has been directly observed. All planets (exoplanets) have been detected using non direct methods or inferred methods.
The observed retrograde motion of planets led Ptolemy to add epicycles to Aristotle's system. Epicycles were small circles that planets moved in on their larger circular orbits around Earth in order to explain the appearances of retrograde motion.
Mars does not revolve around any planets, it is a planet in its own right. If it did, it would be called a moon. It orbits the sun directly.
The planets are satellites of the sun. The moons are satellites of the planets. The moons revolve around the planets captured by their gravity, while the planets revolve around the sun captured by its gravity and the sun.
The planets,asteroids,and comets. There is nothing that doesn't orbit the sun.
The collection of planets and their star (primary) are called a solar system. The planets themselves are called "exoplanets." Once we can tell they fit our definition of planet (having cleared their orbits, etc.) we would probably just refer to them as planets.
No, planets orbit around the sun directly.
The moon does not orbit directly around the sun.
Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.
Yes, there are over 200 more planets outside the solar system, these planets are called extrasolar planets. There are also more then 170 solar systems inside of the Milky Way, on average astronomers find around 25 new planets a year.

"Exoplanets" are planets around stars, outside of our solar system. They are also called "extrasolar planets", "extra" here meaning "outside". It is an imaginary planet created by SM entertainment for their new K POP group EXO. It is said to be the homes of these 12 members
It is extremely likely, but we cannot yet find planets from that far away. All the planets we have found to date are in our own galaxy. The Andromeda galaxy is 2.5 million light years away whereas our galaxy is about 100,000 light years across.
No planets revolve around earth they revolve around the sun.
They all do, its one of the things that is required for a planet to be a planet, directly orbiting the sun.
Gravity is a force that cannot be seen directly, but its effects can be observed. We can see the effects of gravity when objects fall to the ground, planets orbit around stars, or when tides are created in the oceans due to the gravitational pull of the moon.
