Question

Which is the last planet of solar system?

Answer 1

Not pluto. Pluto is no longer called a planet.

Answer 2

They all formed at the same time.  When the sun goes red giant, Neptune should last the longest since it's the farthest from the sun.  

Answer 3

Recently Pluto was changed to a dwarf planet meaning it is no longer a planet (such as the others), but is in a category by itself.

Therefore leaving Neptune to be the farthest planet from  the sun.  

Answer 4

Planet X...  

Answer 5

Neptune

Answer 6

It is either Pluto, or Neptune. This is for many reasons, one is that some scientists don't think that Pluto is large enough to be considered a planet. Also Neptune's and Pluto's paths cross, so at some points, Neptune is farther. There has also been proof that there is a new planet, a tenth one, and it's name is basically a bunch of letters and numbers. But some people either haven't adapted to that, or don't believe it's true.

Answer 7

i sort of think it was the earth, since it is so complex. then again, i also think the other ones are only there to balance,protect,..., earth and life.  

Answer 8

sedna?

Answer 9

Alphabetically, Venus.

Reverse alphabetically, Earth.

From smallest to largest, Jupiter.

From largest to smallest, Mercury.

I assume though, you meant the farthest away from the sun, which is Neptune.
