Dwarf Planet Pluto

Comets. We think.

Let's be clear about this; the "Oort cloud" is entirely THEORETICAL. It makes perfect sense that there must be SOMEPLACE that comets are coming from, since it's impossible that the same comets have been swooping past the Sun for the last 4.5 BILLION years. But as of yet, we have no actual EVIDENCE of the area known as the Oort Cloud. Nor, given the distances involved, is it even possible for us to GET the evidence given our current technology.

As scientists, we can be fairly confident that when we get out there, either in person or by robot, we'll find a vast area with a few billion speckles of dirt, rocks, ice - you know, comet stuff. Then we will have some evidence that the Oort cloud theory is correct. But we're not there yet.

Lots of people studied planets. In fact, just about any renaissance scientist you've ever heard the name of (and a lot more) probably studied the planets at least a little bit. So if you were hoping for us to pick one out of the crowd for you ... sorry.

There isn't.

The "surface gravity" is dependent on the mass (of the planet, etc.) and the distance of the surface from the center of mass. Pluto has MUCH LESS mass than Earth and the gravity is much less on Pluto.

From Wikipedia: "Spectroscopic analysis of Pluto's surface reveals it to be composed of more than 98 percent nitrogen ice, with traces of methane and carbon monoxide." Further down, it is believed that there is water ice, and finally a rocky core.

Approximately 3 Earths could fit inside Jupiter's iconic red spot, also known as the Great Red Spot. This means the spot is vast enough to hold an impressive amount of Earth-sized objects within its boundaries.

Mars already has an atmosphere. It is not known how long creating an Earthlike atmosphere because we do not have the ability to terraform planets and we do not know all of the challenges it might hold.

Dioptis charon was created in 1893.

• Characterize the global geology and morphology of Pluto and Charon
• Map chemical compositions of Pluto and Charon surfaces
• Characterize the neutral (non-ionized) atmosphere of Pluto and its escape rate

Jupiter is the largest planet in our solar system with a diameter of about 86,881 miles (139,822 kilometers), which is about 11 times the diameter of Earth. In terms of mass, Jupiter is much more massive than Earth, with a mass of 318 times that of Earth.

The record of Pluto's rise and fall as a planet

No,pPlanets are NOT elliptical in shape, they are basically spheres. However their spherical shape is distorted by the centrifugal forces resulting form their spin. This makes their equators fatter and their shape becomes that of an "Oblate Spheroid".

The Earth is an oblate spheroid. It is a sphere, but measured around the equator it is slightly larger than measured along the Prime Meridian/International Date Line.

Saturn is a gas giant planet, meaning it is primarily composed of hydrogen and helium with a small rocky core at its center. It does not have a molten surface or significant internal heat source like a molten giant planet.

they are important because earth is a terrestirial planet, if there was no earth, we willnot be here.

They agreed a new definition of a planets and created "dwarf planets" as a separate type of object. Pluto qualified only as a "dwarf planet", because it is not the dominant object in the neighbourhood of its orbit.

Science Priorities

Based largely on what the scientific community wanted to learn about Pluto and Charon, NASA prioritized its science goals for Pluto-system exploration in three categories:

Required

• Characterize the global geology and morphology of Pluto and Charon

• Map surface composition of Pluto and Charon

• Characterize the neutral atmosphere of Pluto and its escape rate

Important

• Characterize the time variability of Pluto's surface and atmosphere

• Image Pluto and Charon in stereo

• Map the terminators (day/night lines) of Pluto and Charon in high resolution

• Map the composition of selected areas of Pluto and Charon at high resolution

• Characterize Pluto's ionosphere and solar wind interaction

• Search for neutral species (including hydrocarbons and nitriles) in Pluto's upper atmosphere

• Search for an atmosphere around Charon

• Determine bolometric bond albedos for Pluto and Charon

• Map the surface temperatures on Pluto and Charon

Desired

• Characterize the energetic particle environment of Pluto and Charon

• Refine bulk parameters (radii, masses, densities) and orbits of Pluto and Charon

• Search for magnetic fields of Pluto and Charon

• Search for additional satellites and rings

NASA defines mission success as meeting the "required" objectives. With its full science payload -- three optical instruments, two plasma instruments, a radio science receiver/radiometer and a dust sensor - New Horizons expects to exceed these requirements, meeting or addressing all of the objectives in each category.

Uranus. 17h 14m 24s for one spin on its axis.

1. check the fuse(s), usually marked radio 2. check the connections to radio 3. try another radio or yours in another car to make sure the radio can work 4. check ALL fuses in the block, there may be a line going to it that is covered in a general fuse 5. check the ground, make sure its connected ETC.

Yes, dwarf planets can have a variety of shapes besides being round. Factors like their size, composition, and unique geological history can influence their shape. Some dwarf planets may have irregular shapes due to impacts or gravitational interactions with other celestial bodies.

The average distance from the earth to the sun is 93,000,000 miles. If you could completely break out of orbit and travel a short, perfectly straight line to the sun, pottering along at 60 miles per hour, it would take 93,000,000 / 60 = 1,550,000 hours = 64,583 days = about 177 years to get there.
