Dwarf Planet Pluto
A dwarf planet that was the 9th planet from the Sun in our solar system until 2006 when it was determined it did not satisfy the requirements of being a planet.

What would happen if you stood on your head while eating?
Your esophagus (the thing that brings food down when you swallow) uses muscles to bring/keep food down into the stomach, so your esophagus basically pinches together above the food and pushes it down like a tube of yogurt. If you ate food upside down, than it wouldn't just come right back out, it would still go down to the stomach like normal.
A meter is a measure of distance. There are 1000 meters in a kilometer. Thus 63000000 meters is 63,000 kilometers.
To understance the scale of that distance, the average distance from Earth to the Moon is 384,400 km so it is about 1/6 of the distance to the Moon.
Do moons have to orbit a planet?
Yes, because if they didn't they wouldn't be moons, they would just be chunks of rock or whatever they are made of.
Is Pluto only larger than Mercury?
Pluto is not larger than Mercury. Pluto is the smallest planet in the solar system and it only has a diameter of 1413 miles.
Whom does Dr Tyson credit with first noticing that Pluto was not included in his museum exhibit?
Seven year old boy will galmot
What is name the satellite of Pluto?
Two smaller moons discovered in recent years were named Nix and Hydra and another two remain unnamed.
How long does it take to communicate with Uranus?
Uranus is 1.7 billion miles from Earth.
Radio waves travel at the speed of light-about 186,000 miles/second
Therefore it will take approximately 2.5 hours for someone on Earth to communicate with Uranus.
Is Pluto one of Jupiter's moons?
No! It used to be a planet and know it is a dwarf planet. It is at the edge of the solar system, and is pretty (as in really) far away from Jupiter.
It is small enough to be one of Jupiter's moons
Hi, just wanted to add something- why would you even think Pluto was one of Jupiter's moons?! They are nowhere near eachother. I would be ashamed if I asked such a dumb question like this.
How long would it take approximately for light to travel from here to New York?
Light travels at approximately 186,000 miles per second, or approximately 3,000,000 (3-million) meters per second, or almost 1,000,000,000 (1-billion) feet per second. That's about 1 nano-second (1 billionth of a second) per foot.
Light almost always travels in a straight line, but light is affected by gravity, and the path of the light can be "bent" (curved) as the light passes near large planets, or stars, or "black-holes".
The distance around the earth at the equator is about 25,000 miles, so in 1 second, light will travel an equivalent of distance of about 7 and one-half times around the earth.
Our Moon is about 250,000 miles away. Light from the Moon takes about 1 and one-third seconds to reach earth.
Earth's orbit around the sun is not perfectly circular so the distance between the Earth and the Sun varies slightly over the course of the year. The average
distance between the Earth and the Sun is about 93,000,000 (93-million) miles, so it takes about 500 seconds (8 and one-third minutes) for the light from the Sun to reach Earth.
In your question, you asked how long it takes light to travel to New York, but you didn't specify the starting point. So, to calculate the time for light to travel from where you are, to New York...
Find the distance (in miles) from where you are, to New York, multiply that distance by 5,280 (that is the number of feet per mile), and that will give you how many nano-seconds it takes light to travel that distance.
As of Sept 2017, the surface has only been observed from orbit, but it appears that there is flat ground on Pluto.
What are the four criteria that must be met in order to be considered a dwarf planet?
i clearly dont know the answer if im asking the question
How many times can Pluto fit into Venus?
About 150, if you go by volume:
Pluto: 6,390,000,000 square kilometers
Venus: 928,000,000,000 square kilometers
If you wanted to keep all the Plutos spherical, so there would be gaps between them like marbles in a fishbowl, that's too much math for me to do right before supper.
What satellites have gone to Pluto?
None. No satellites have ever gone to Pluto. But the New Horizons spacecraft went there, and arrived on July 14, 2015. It flew 12,500 km (7,800 mi) above the surface of Pluto, making it the first spacecraft to explore the dwarf planet.
On October 25, 2016, at 21:48 UTC, the last of the recorded data from the Pluto flyby was received from New Horizons. Having completed its flyby of Pluto, New Horizons has maneuvered for a flyby of Kuiper belt object (486958) 2014 MU69, expected to take place on January 1, 2019.
Why did Dr. Tyson decide to exclude Pluto from the exhibit of plants?
because it displayed an icy body rather than a planet
Why were transitions which ended at energy level 1 not studied by the unaided eye?
Transitions that end at energy level 1 are in the UV or X-ray range, which is outside the visible spectrum detectable by the human eye. Our eyes can only perceive electromagnetic radiation within a certain range of wavelengths, typically from about 400 to 700 nanometers, corresponding to the colors of light in the visible spectrum. UV and X-ray wavelengths are much shorter and higher in energy, making them invisible to the naked eye.
Why has Pluto been reclassified as a dwarf planet?
Pluto is a dwarf planet by definition, but it is also a : * TNO or Trans-Neptunian Object - orbit the Sun outside the orbit of Neptune; once orbits are determined they are given permanent "minor planet" numbers, and if candidates for dwarf planets, they are named. * KBO or Kuiper Belt Object - inhabits the innermost of three Trans-Neptunian regions (the other two are the "scattered disc" and the Oort Cloud). * plutoid - a trans-Neptunian dwarf planet or candidate * plutino - a trans-Neptunian body locked in 3:2 orbital resonance with Neptune, such that for every 3 Neptune solar orbits, the body orbits the Sun 2 times (a important factor in maintaining orbital stability)
What is the satellites or rings of Pluto?
Pluto has no known rings and it is doubtful that any will be discovered because of Charon. Charon is Pluto's moon or more properly they might be called the Pluto-Charon binary system. The gravitational center of the two bodies is not in the volume of Pluto but in space between it and Charon (for comparison the Earth -Moon system has a common gravitational center - a barycenter - that is a thousand kilometers under the surface of the Earth.
Nobody knows. No human has ever been to Pluto, and no probes have ever landed on Pluto.
Why was Pluto named after the Roman and Greek god of the lower world?
All the planets visible to the naked eye have been associated with the gods since ancient times. After the invention of the telescope, when scientists began to find new planets they followed a tradition of also naming them after the gods. When Pluto was discovered, it was given the status of a planet, although it has since been reclassified as a dwarf planet. Since Pluto is so distant from the sun, it is a dark planet, receiving little light from the sun, so the scientists felt that the god of the underworld, Pluto, would be the most appropriate god to name the planet after.
