The best way to tell the difference is by tracking the object.
If the object seems to move in an orbit around the Sun, then it is in the solar system. If not, it is outside it.
No one knows it. Scientists lie or exaggerate about knowing. Although the above is partially true, scientists do have theories about how the solar system was formed. If the entire solar system was formed at the same time then all objects in the solar system are the same age. Using radioactive dating of meteorites scientists calculate how long it has been since the meteorite solidified and go based on that date.
because of scientists
the difference between our solar system and the scientists is that we put terrestrial and gas giants where as they only put planets. Do u guys know any other ones?
It doesn't have one. The NGC numbers are used to describe objects in outer space - as seen from Earth. Nor are individual objects in our Solar System included, as far as I know.
No scientists say that. Scientists know that Pluto is a dwarf planet, and not one of the 8 major planets of our solar system.
yes, there is but scientists are still discovering it----
yes
The big bang, a massive explosion creating all life as we know it.
to make sure that every one know there are more planets
The only natural object we know of that does that is the earth's moon.
scientists use spacecraft without people to explore space because scientists need to know more about space and the solar system
so we know where the planets, moons, asteroids meteorites, comets, and other objects are situated. This will give a direction and information about traveling in our solar system and the time it takes to travel there.
