Is there vegetation on Neptune?
No, Neptune is a gas giant composed primarily of hydrogen and helium with no solid surface. Its atmosphere is mainly hydrogen, helium, and methane, with no known vegetation able to survive in such extreme conditions.
When Voyager 2 (launched in 1977) passed Neptune how long had it been traveling?
just lon enough to get it through uranus :)
Did the voyagers fly by Neptune or landed in Neptune?
Neptune isn't dense enought (not solid enought ground) to stand on so it couldn't so it just flew by and there were 2 voyagers that went out when the planets were aligned in a perfect way to easily get from on to another
Does Pluto and Neptune swap places every 9 years?
They don't. What actually happens is that Pluto's orbit... well, it doesn't actually intersect Neptune's, but on a two-dimensional plot it looks like it does. This means that for a brief period on each of its orbits around the Sun, Pluto is closer to the Sun than Neptune is.... they do not, however, "switch places."
(Also, despite what you might think if you looked at a graph, Pluto never gets anywhere near Neptune. The closest Pluto can ever get to Neptune is about 17 AU; it actually can get nearer to Uranus ... about 11 AU... than it can to Neptune. The reason for this is that Pluto is in a resonance orbit with Neptune; it makes three complete orbits for every two of Neptune's, so every time Pluto is at one of the "crossing points", Neptune is somewhere else in its orbit.)
Great Red Spot and great Dark Spot?
The Great Red Spot is a massive storm on Jupiter that has been raging for hundreds of years. It is a high-pressure system that is larger than Earth. The Great Dark Spot was a storm on Neptune that was observed in 1989 by the Voyager 2 spacecraft. It was a large, dark storm system that eventually dissipated.
Why might it change that Neptune isn't the farthest planet from the sun?
Neptune is always the farthest planet from the Sun.
But the dwarf planet Pluto will eventually grow in size as it continues to orbit and collect and grow from floating materials in space (e.g. smaller meteors landing and collecting on Pluto increase it's size). It isn't a planet now but could eventually grow to the size of a planet and regain its planetary status, making Neptune not the farthest from the sun.
Why does Neptune or Uranus appear bluish or greenish in color?
They appear blue because they are made up from:
1. Hydrogen and helium
2. Water and ammonia
3. And the middle is a molten ammonia core
Neptune is composed primarily of rock and metal in its inner core, surrounded by a mantle of water, ammonia, and methane ices. Its atmosphere is primarily composed of hydrogen, helium, and methane gases, with traces of other elements and compounds. The extreme pressure and temperature within Neptune create unique conditions that affect its composition and behavior.
Why does a person's urine appear green for no apparent reason?
The normal color of urine ranges from light yellow to dark amber, depending on the concentration of solutes in the urine. Certain medications contain dyes, such as methylene blue, that may cause the urine to turn green for one or more days. Green urine could also indicate a urinary tract infection, bile problems or an excess of B vitamins. A physician should be consulted if a person's urine appears green.
Who discovered complete rings around neptune?
Complete rings around Neptune were discovered in 1989 by the Voyager 2 spacecraft during its flyby of the planet. The rings are comprised of four main rings and were the first to be discovered around Neptune.
Is the Sun nearer to the Earth than Neptune?
The sun is much closer to earth than Neptune is. Neptune is way out there. The sun is 1 A.U. away or 92 milllion miles Neptune is between 29 - 31 A.U away
What is the length of a year an day on neptune in earth years?
Each day on Neptune takes 19.1 Earth hours. A year on Neptune takes 164.8 Earth years; it takes almost 165 Earth years for Neptune to orbit the sun once.
Since Neptune was discovered in 1846, it has not yet completed a single revolution around the sun.
According to the astronauts, there is a very small chance that at one time Pluto will ever come close to Neptune. This assertion has been discussed in many forums bearing in mind that their orbit intersects. Gravitational resonance is the condition that prevents Pluto and Neptune from colliding.
Was Neptune named after the god Neptune?
Neptune is named after Neptune, the Roman god of water and the sea, the brother of Jupiter and Pluto. Neptune's equivalent in Greek mythology is Poseidon.
Neptune was named after a sea god because the planet looked like a big blue ocean.
What gas can give a planet a blue appearance?
No, I think it is because plant cells contain chloroplasts which have chlorophyll which make the chloroplasts green so therefore the whole plant is green. Possibly. Sorry if this is not satisfactory information, I'm only 11.
How far is Venus from Neptune in km?
That depends on where they are in their orbits of the Sun. At certain times they are on opposite sides of the Sun form each other and at other times they are on the same Side of the Sun so the distance between them is constantly changing.
This said, Mercury orbits at an average of about 0.39 AU from the Sun and Neptune at an average of about 30 AU from the Sun.
1 AU = 149597871 kilometers
How are Neptune and mercury different?
Both Neptune and Mercury are fairly different, but there are a few things that are similar between them. For instance, They both orbit the sun, are part of the solar system, they are both named after Greek gods, and they both have similar gases (hydrogen,helium,oxygen,methane) hope this was helpful :))
What type of gasses does neptune have?
Neptune is made up of a gas called Methane, which makes it the bluey colour. the core of Neptune is made out of hot melted rock, the top layer is made out of hydrogen and helium, with a little bit of Methane mixed into it.
Since Pluto is not a planet what is the smallest planet?
Mercury is the smallest of the 8 "major planets" with about 5.5% of the mass of Earth. It is smaller but more massive than the largest moons of Jupiter and Saturn.
Pluto is now considered a "dwarf planet" along with the asteroid Ceres and three other very distant Kuiper Belt objects.
What describes Uranus and Neptune?
Has blue color gas made of melanin that smells like girls nail polish. If you like it, then you're an idiot!
The name Neptune is from the Roman god of the Sea, Neptune
