Could there be more large planets in our solar system undiscovered?
Question:
Answer:
Let's consider the possibilities and address them one at a time.
1) There is a large planet on the opposite side of the sun from Earth.
This has been proven not to be the case. Such a planet would cause the other planet's orbits to "wobble" in ways that have not been observed and besides, none of the probes which have been sent to other planets has observed any planets "hidden" behind the sun.
2) There is a large planet in the outer reaches of the sun's gravitational field.
While this is in fact a possibility, it is highly unlikely. Typically when "solar" systems are formed, the distribution of the planet sizes follows a roughly gaussian distribution, with the larger planets in a huddle (in our case, Jupiter, Saturn and to a lesser extent Uranus and Neptune). If there was a large planet in our solar system out beyond Pluto, it would be difficult to see, however there would be no other stars near enough to pull it away from the sun. It may, for example be hidden by the sun, but so far away that no "telescopes" on probes are powerful enough to see it (refer to option 1 above).
3) There is a large planet made of anti-matter in the inner solar system (closer to the sun than Pluto) which we cannot see.
This is not possible. The visible planetary orbits would be perturbed, and we don't observe that.
4) I have run out of options.
This is VERY possible!
So, there you have it. Make up your own mind.
Could be, maybe there's a norther earth we don't know about and I'm serious! Who knows.
This would be almost impossible for the years of scientific observation and rigorous experimenting that has mapped out the whole universe to miss a large planet in our own solar neighborhood.
Could Be , Maybe Outside of this galaxies . Theres believes that galaxies is infinity
yes it is possible in universe for next time
you havn't found mine yet
No...it would be virtually impossible at this point in time. Even if there were more, they would be so far away from the sun that their size and importance would be insignificant.
Could be
It has been suggested that the sun has a twin mass , consisting of anti-matter, far out ,inside the outer reaches of our s.s., I'm talking way past Pluto, that keeps spacial time in check.
"There might be planet undiscovered in our own solar system" the problem with this assumption is that every celestial body can exert a gravitational pull strong enough to get another smaller celestial object to rotate around it, only for a limited distance. In the case of our Solar system - the Sun can only attract may be till a little farther than Pluto beyond which logically speaking another large planet can conviniently breakaway from the Sun's gravitational pull
No. Any "extra" large planets would have obvious gravitational effects on the known planets. For example, the existence and even position of Neptune was predicted before its discovery based upon irregularities in the orbits of the other planets. A interesting scenario would be to place the extra planets very far from the Sun, far beyond Neptune, but then they would be loosely bound to the Sun and probably lost during encounters with other stars.
Depends where you call the edge of the Solar System
