All i know is alot!
well since neptune is almost the farthest planet................................probaby.......................................oh i dont know. silly me answering is for nerds
Yes, every object in the universe has a gravitational pull on every other object. However, Neptune is so much smaller than the Sun, and so much farther away, that Neptune's gravitational pull on Mercury will be unmeasurably small.
Neptune is the eight planet from the sun
Neptune is about 3.88 times larger than the Earth, so about 58.5 Earths could fit inside Neptune.
Temperature relies on distance from the Sun. In order the planets are ... Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto So Mercury is hottest as it is closest to the Sun Mars is closer than Neptune, so is hotter. So Neptune is colder.
Techinically, Forever. But, we don't know that Neptune exists, so we can't say for sure.
Saturn is much larger than Neptune so it likely has more gas since they are both gaseous.
i think you can get radio signals from neptune because a space thing said so. well i need to know the answer because im doing a project.
nothing , there is no unsustainable life that we know of on Neptune
it would take us nearly 8 months to get to mars so imagine how long it would take to get to neptune. plus the climate is much much colder so it's not really possible in the near future
No known living organisms can survive on the planet Neptune due to its extreme cold temperatures, lack of sunlight, and inhospitable environment. Neptune's atmosphere is composed mostly of hydrogen, helium, and methane, making it unsuitable for any form of life as we know it.
