Dwarf Planet Pluto

Both Neptune and Pluto were discovered in the early 20th century. Neptunium and Plutonium were later named after these planets by scientists involved in the discovery of these elements, reflecting the trend of naming newly discovered elements after celestial bodies around that time. The names also carry on the tradition of using Roman mythology in naming elements.

Planets in our solar system are on stable orbits and are not expected to collide with each other. However, in the broader universe, planet collisions can occur when two planetary bodies are on a collision course or if a disruption in their orbits leads to a collision. The likelihood of such events depends on various factors, including the density of objects in space and their trajectories.

Pluto is still in our solar system. However it is not considered a planet anymore due to the fact that over the last few decades, powerful new ground and space-based observatories have completely changed previous understanding of the outer Solar System. Instead of being the only planet in its region, like the rest of the Solar System, Pluto and its moons are now known to be just a large example of a collection of objects called the Kuiper Belt. This region extends from the orbit of Neptune out to 55 astronomical units (55 times the distance of the Earth to the Sun).

Astronomers estimate that there are at least 70,000 icy objects, with the same composition as Pluto, that measure 100 km across or more in the Kuiper Belt. And according to the new rules, Pluto is not a planet. It's just another Kuiper Belt object.

Pluto takes more than a day to rotate. It takes about 6.39 Earth days.

Both Pluto and Neptune were discovered by observing deviations in the movement of other planets from what they were calculated to be, and from that calculating where something else should be that was causing those deviations.

Mercury is considered the smallest rocky planet in our solar system. It has a rocky core and is closest to the Sun.

The invention of the telescope by Galileo Galilei in the early 1600s helped early scientists discover more planets. By using telescopes to observe the night sky, astronomers were able to see celestial objects more clearly and detect planets that were previously invisible to the naked eye.

The orbit of a planet is highly eccentric when it is more elongated rather than circular. This means the planet's distance from the sun varies significantly throughout its orbit, resulting in periods of being closer and then farther away from the sun.

the planet takes almost 2 earth years to orbit the sun is Jupiter

A substance's composition is what it is made out of. Koolaid's composition is water and koolaid powder.

Alternatively, it could mean what someone makes, although that is much less common. By that I mean, a song would be a musician's composition.

It takes Jupiter just 3 earth days to orbit the sun. Even though Jupiter is many millions of kms farther away than earth from the sun, the suns gravitational pull on Jupiter is more massive as Jupiter is thousands of times larger than the earth.

Like the planets, Pluto's spin axis stays pointed in the same direction as it orbits the Sun. But unlike all planets except Uranus, Pluto is tipped on its side. The planets' axes of rotation stand more or less upright from the plane of their orbits.

Pluto's minor gases include methane, carbon monoxide, and nitrogen. Its major gas is nitrogen, which makes up the majority of its thin atmosphere.

I just learned this while researching grow lamps today.

The conversion from nm to K is:

SInce I'm typing this out on a computer, and don't really know how to turn on my funny math symbols, I'm going to rewrite the equation below, with everything in the same place, only replacing the funny symbols with other variable symbols that I can reproduce on a regular keyboard.

nm = 2,897,768 / K

In this equation:

nm = nanometers, or peak wavelength

K = Peak temperature, in degrees Kelvin.

2,897,768 = the number that needs to be in the equation according to some big science and math conference where a whole lot of nerds got together and decided things like the number that needs to be in that spot in the equation. I tried to understand it, but I don't know anything about math terminology and am not smart enough to learn about it tonight before I respond to this, so I can't explain why that number exists, only that it has to be there to complete the conversion.

This equation is called Wien's law, and it is actually a lot more complex than I'm making it here, but to use it properly would take more understanding than I have. This method is not as accurate as if you were to use the full equation, but it's so close that most people even simplify it further to nm = 3,000,000 / K, and still consider it accurate enough to be a practical reference tool.

I'll show a few examples.

A light bulb rated at 4500K translates to 644nm.

644 (nm) = 2,897,768 / 4500 (K)

A light bulb rated at 6500K translates to 446nm.

446 (nm) = 2,897,768 / 6500 (K)

A light bulb rated at 10.000K translates to 290nm.

290 (nm) = 2,897,768 / 10,000K

The sun puts out peak radiation at 5778K, which is approximately 502nm.

502 (nm) = 2,897,768 / 5778 (K)

Adversely, to convert the opposite direction, swap the position of the nm and the K to look like:

K = 2,897,768 / nm

The response to your question would look like this: K = 2,897,768 / 450

K = 6,439K

You'll notice that when you make it a little easier on yourself and use 3,000,000 instead of 2,897,768, the result is quite noticeably inaccurate, but I suppose if you needed that much accuracy, you'd be in a lab somewhere doing this yourself instead of asking a moron like me to explain it.

Yes, Pluto has been determined to be in hydrostatic equilibrium. Planets must orbit the sun (the first criterion for a planet), and must also be in hydrostatic equilibrium (which Pluto is). Pluto fails the third "planetary entrance test" set by the IAU in that it has not cleared its orbit of debris. A link can be found below to check facts and learn more.

Hebe was the Greek goddess of youth and the cupbearer of the gods. She was the daughter of Zeus and Hera and was known for serving nectar and ambrosia, the food and drink of the gods. Hebe was also seen as a symbol of eternal youth.

Neptune. It was discovered in 1846, and will not complete its first orbit around the Sun since then until next year, giving it an orbit duration of roughly 165 years.

It is planet Pluto.

______________________

There are five "dwarf planets" in our solar system, as of August 2010. There are certainly dozens or hundreds more in the distant parts of our solar systems, but our telescopes are not yet good enough to see them.

Pluto was considered a planet until the International Astronomical Union (IAU) reclassified it.

Ceres was an asteroid before the IAU reclassified it.

The Kuiper Belt Objects later named Eris, Haumea and Makemake were all considered to be candidates for being named the "Tenth Planet" until the IAU came out with its definition of "planet". In fact, it was the discovery of the dwarf planet Eris, originally called "Xena", that caused the IAU to finally come up with a formal definition of "planet". All three of these objects are now considered to be "dwarf planets".

There are several other large asteroids that probably deserve "dwarf planet" status as well; Vesta, certainly, and Pallas, and perhaps a few others.

A black solar still typically works better than a clear one because black materials absorb more sunlight, leading to greater heating and evaporation within the still. This increased heat helps to speed up the distillation process and improve the overall efficiency of the solar still in producing clean water.

The prefix "pluto" means wealth or wealthy

Not all planets are. Warmth depends entirely on the atmosphere and how close it is to the star. for example, Mercury's daytime and nighttime are about 600 degrees Celsius apart, being about 300 C and -300 C respectively, and Venus has so much carbon dioxide, that the surface is three times as hot as on mercury, which means venus's surface would feel like a mushy candy bar left in the sun. however, Earth, whithout an atmosphere, would have an average temp of -18 degrees AT THE EQUATOR. this is why greenhouse gasses are important, because that is why we have nice temperatures like an average of 54 degrees Fahrenheit planetwide. Past us, most of the rocky planets ( and dwarf planets) have little to no atmospheres, so they have temperatures very close to absoulte zero. outside our solar system, a very common sight is a 'hot Jupiter' meaning a Jovian planet of around Jupiter's mass that orbits it's sun in less than an earth day. being this close has many consequences, one of which being if they are low-density they have a very good chance of being blown apart by solar winds. one such planet has an average daytime temperature of about 2400 degrees C, about 1000 degrees less than it's own parent star.

Jupiter and Saturn have more moons than the terrestrial planets. Jupiter has over 80 moons, while Saturn has over 80 confirmed moons as well. This is far more than the terrestrial planets in our solar system, such as Earth, Mars, Venus, and Mercury, which have few or no natural satellites.

perhaps it means that it was a 3 piece unit but since it all goes together, because maybe it was all purchased together-- all the pieces should be combined and classified and shipped as a single unit.

this could also be because all the pieces have the same style and color and therfore should be categorized as a combined set unit

-- or corporate Headquarters could have changed their mind and decided that from now on this 3 piece unit will be sold together as one single unit which would classify it as a single piece shipment
