Who said that electrons orbit an atom like planets orbit the sun?

This description of electrons orbiting an atom like planets orbiting the sun is commonly associated with the early atomic model proposed by Niels Bohr in 1913. Bohr's model suggested that electrons move in circular orbits around the nucleus similar to how planets move around the sun. However, this model was later replaced by the more accurate quantum mechanical model.

What is Eris orbital speed?

Ceres orbits the sun at a speed of 12345km an hour.

NOT YOU JUST GOT OWNED YOU NOOOOOOOOOOOOOOOBS! GO HUMP A COW!

Has Voyager 2 reached Pluto?

Voyager 2 never went to Pluto. Given the positions of the planets in their orbits at the time, we could not send it on a trajectory to get there. Currently Voyager 2 is well beyond the orbit of Pluto and will soon enter interstellar space.

Name given to a distant sun?

A distant sun can be referred to as a star. Stars are luminous celestial bodies composed of hot gases that emit light and heat energy. They play a crucial role in the universe by providing light and energy to planets like our own Sun does for Earth.

What are some facts about the moons of Pluto?

Here are some facts about Pluto:

  • In 2006, got reclassified from a "planet" to a "dwarf planet".
  • Pluto gets closer to the Sun than Neptune about 10% of its orbit.
  • The temperature is around -230°C (-382°F).
  • Pluto is smaller than the Earth's Moon.
  • New Horizons was the first spacecraft to visit Pluto and sent back very good images of the surface.
  • Pluto is 3,670 million miles away from the Sun.
  • It takes 248 Earth years for Pluto to orbit around the Sun.
  • One day on Pluto is about 6 and a half earth days.
  • Pluto has 5 moons: Charon, Hydra and Nix Kerberos and Styx.
  • Pluto and Charon spin on an axis of about 123 degrees.
  • Pluto has a large rock core, an icy mantle and an icy surface.
  • Pluto and Charon orbit together so both of them only see one side of each other.
  • Because of Pluto's weird orbit, it is sometimes closer to the earth than Neptune.

How long for it to rotate on axis for Pluto?

Pluto rotates on its axis once approximately every 6.4 Earth days. This slower rotation period is one of the contributing factors to its unusually long day length.

Which planet's orbit looks the least like a circle?

Mercury's orbit looks the least like a circle compared to other planets in our solar system. Its highly elliptical orbit is the most elongated, meaning it is more stretched out and not as round as other planets' orbits.

Which planet is not a frozen planet?

Well, obviously, Earth isn't a frozen planet. Neither is Venus. Mercury gets much bellow freezing in the night but at day it's temperature is around 400 celsius. Mars is almost always bellow freezing. The planets keep getting colder past Earth, as it gets further and further away from the sun.

How old is Pluto and why do they call Pluto a dwarf planet?

Pluto is about 4.5 billion years old, roughly the same age as the rest of our solar system. It is called a dwarf planet due to its small size and its location in the Kuiper Belt, a region beyond the orbit of Neptune where many similar small icy bodies are found.

In 2178 will Pluto be in the same place it was when discovered?

Pluto was discovered in 1930. Pluto takes 248 Earth years to orbit the Sun. So yes, in 2178 it will be in the same place in its orbit and will have completed one revolution around the Sun (its year) since it was discovered.

How many planets are there bweteen Pluto and the sun?

There are eight planets between Pluto and the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto used to be considered the ninth planet before being reclassified as a dwarf planet in 2006.

How much brighter is a Sun-like star than the reflected light from a planet orbiting around it?

A Sun-like star is typically about a billion times brighter than the reflected light from a planet orbiting around it. This difference in brightness makes it challenging to directly image exoplanets due to the overwhelming glare from their host stars. Techniques such as using coronagraphs or starshades are employed to block out the star's light and improve the chances of detecting planets.

Which planet has the most suns orbiting around it?

Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.

The reason that small planets tend to lose interior heat faster than larger planets is essentially the same as the reason that?

small objects cool faster than large objects: their smaller size-to-surface area ratio means they have less capacity to retain heat. The larger surface area of small planets relative to their volume leads to more efficient heat loss. This results in faster cooling of their interiors compared to larger planets.

What does a planet with a large orbit around the sun have?

A planet with a large orbit around the sun likely has a longer year or orbital period, meaning it takes more time to complete one revolution around the sun. This may result in colder temperatures due to being farther from the sun, and potentially more elliptical or stretched-out orbit.

A planet with a large orbit around the sun has?

A longer orbital period, meaning it takes more time to complete one revolution around the sun. This results in a larger average distance from the sun compared to planets with shorter orbits. This increased distance can lead to colder temperatures on the planet.

Earth is 1.5 x 1 km from the sun and Pluto averages 5.9 x 10 km from the sun during its rather strange orbit?

Pluto orbits the sun at an average distance of about 5.9 billion kilometers, while Earth is around 150 million kilometers away from the sun. This makes Pluto's average distance from the sun significantly farther than Earth's.

What planet did S gt forge blow up?

Sgt. Forge sacrificed himself to detonate a slipspace drive aboard the Covenant ship, destroying it above the planet Harvest in the Halo franchise. The planet was not blown up, but the Covenant ship and a significant portion of the planet were destroyed in the process.

Why did astronomers begin searching for a planet X?

Astronomers began searching for Planet X to explain discrepancies in the orbits of Uranus and Neptune. Observations indicated the presence of an unknown massive celestial body affecting the orbits of these planets.

How distance affects the revolution time on the planets?

The distance of a planet from the Sun affects its time to revolve around the Sun because the circumference of its orbit is larger; hence, the planet has to travel a longer line to complete one revolution.

Earth, for example, travels along its orbit at over 29 kilometers per second. The planet Mars travels along its orbit at about 24 kilometers per second, so not much slower. However, Mars is farther away and hence its journey is longer, so it still takes about 687 days for Mars to complete one revolution versus Earth's 365 days.

This only addresses how distance from the Sun can influence the revolution time -- tidal effects on the planets also affect how quickly they move along their orbit.

What is the name of Underworld 4?

Right now it is just called underworld 4 but when it is realised i think it will have a full name.

How do Eris and other large Kuiper belt objects compare to Pluto and Charon?

Eris is similar in size to Pluto and about the same distance from the sun, while Charon is much smaller. Eris, Pluto, and Charon are all considered large Kuiper Belt objects, with Eris being slightly larger than Pluto and Charon being about half the size of Pluto.

Why does mercury have a greater mass than Pluto?

Mercury has a greater mass than Pluto because Mercury is a dense rocky planet with a compact structure, while Pluto is a relatively small icy dwarf planet with a lower density. Therefore, despite being smaller in size, Mercury has more mass due to its composition.
