When did sarah malcome discover pluto?

Pluto was discovered in 1930 by Clyde Tombaugh.

Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in the Solar System. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto.

Do planets revolve around the sun at the same speed?

No, planets do not revolve around the sun at the same speed. Their orbital speeds depend on their distance from the sun - planets closer to the sun have shorter orbital periods and faster speeds, while those further away have longer orbital periods and slower speeds.

Is planet X a gas giant?

Planet X is the theorized, but unconfirmed, "10th" planet in our solar system (when we had 9 planets total and Pluto was still considered a true planet). This elusive "Planet X" was thought most likely to be a gas giant and probably the cause of Pluto's off-planar orbital tilt. It was also thought to be the cause for some strange behavior with Neptune in respect to the other gas giants. In fact hunting for "Planet 9" was why Pluto was discovered in the first place. It soon became apparent, however, that Pluto was not "massive" enough to have caused the anomalies with Neptune - hence the hunt for Planet X.

Orbit so eccentric that it crosses the orbit of another planet?

A planet with an eccentric orbit that crosses the orbit of another planet would create gravitational interactions and potential collisions between the two planets. This scenario could lead to disturbances in their orbits, potentially causing erratic behavior and possible impacts between the planets.

Is the Earth's moon smaller than Pluto?

it has a one fifth mass of earths moon and one third volume of earths moon

Pluto sometimes approaches nearer to the sun than Saturn because Pluto's orbit is quite eccentric?

Pluto sometimes approaches nearer to the sun than Saturn, because Pluto's orbit is elliptical, somewhat like a squashed circle. Pluto's orbit is also highly inclined at an angle of 17 degrees. Pluto takes 248-years to orbit the sun once, and at its closest point, comes within 30-astronomical units of the sun.

Is Plutos orbit close to being circular or quite eccentric?

No, it is not. NO orbits of natural satellites are perfect circles. (And when NASA manages to achieve a perfectly circular orbit for an artificial satellite, it doesn't stay that way for very long!)

All orbits are ellipses. The Earth's orbit is pretty close to circular; it's only about a 3% eccentricity. On January 4th (or thereabouts) when Earth is closest to the Sun, it's about 91 million miles away; on July 2nd (or about) when the Earth is most distant, it's a little over 94 million miles.

What is the biggest object in kuiper belt?

It is similar to the asteroid belt, although it is far larger -- 20 times as wide and 20-200 times as massive. Like the asteroid belt, it consists mainly of small bodies (remnants from the Solar System's formation). It is home to at least three dwarf planets - Pluto, Haumea and Makemake. But while the asteroid belt is composed primarily of rock and metal, the Kuiper belt objects are composed largely of frozen volatiles (dubbed "ices"), such as methane, ammonia and water.

How many planets do you have beside Pluto?

Pluto is no longer considered a planet. It has been renamed a "dwarf planet" since it shares its orbit with other, similar sized (or larger... Pluto's orbit crosses Neptune's, and Neptune is enormous compared to Pluto) bodies.

There are 8 known planets in the Solar System, and it's considered unlikely that more will be discovered if the current guidelines are kept (anything large enough to "sweep out its own orbit" would have a detectable impact on the orbit of Neptune).

There are around 500 confirmed "exoplanets" (planets orbiting stars other than the Sun).

How much would it cost to go to Harvard out of state?

For the 2021-2022 academic year, the total cost of attendance at Harvard University for out-of-state students is approximately $78,200. This includes tuition, fees, room, board, and personal expenses. Financial aid and scholarships may be available to help offset some of these costs.

Who was plutos mother?

Pluto's mother was Demeter, the goddess of agriculture and fertility in Greek mythology. She was also known as Ceres in Roman mythology.

How do you draw a picture of dwarf planet?

To draw a picture of a dwarf planet, you can start by creating a round or oval shape to represent the body of the planet. You can then add features like craters, surface markings, or moons to make it more detailed. Adding labels for key characteristics like its name and size can also help enhance the drawing.

Pluto is not considered as a planet?

Pluto is way to small to be a planet.Now we have 8 planets in our solar system not 9.Pluto is much smaller then earths moon!If Pluto was just a little bit smaller then Mercury, it would be a planet, but Pluto is TINY compared to mercury.

How far is Pluto away from Eris?

Both Pluto and Eris (a "dwarf planet" even further from the Sun than Pluto) are constantly moving in their own orbits. Sometimes they may be on opposite sides of the solar system, and at other times they won't be too far apart (as planets go).

How long are dwarf planets days and years?

The length of a day on a dwarf planet can vary depending on its rotation speed. For example, on Pluto, a day lasts about 6.4 Earth days. A dwarf planet's year is determined by its orbital period around the Sun, which can range from several Earth years for bodies like Pluto to over 248 Earth years for bodies like Eris.

Will earth be around long enough for the year 3000?

Yes, it is highly likely that Earth will still be around in the year 3000. While we cannot predict the future with absolute certainty, based on current scientific understanding, there is no major event expected that would destroy the planet before then.

You are usally th 8th planet from the sun but every 248 years you move inside plutos orbit for 20 years?

That description fits the planet Neptune in our solar system. Neptune is usually the 8th planet from the sun, but due to its orbital path and the orbit of Pluto, every 248 years it moves inside Pluto's orbit for a period of around 20 years before returning to its usual position.

Is kuiper belt the most distant object in your solar system?

Pluto is still considered to be the the largest KBO, however there are several "scattered" objects that are believed to have come from the Kuiper Belt. For a discussion of the sizes of known KBO's and Scattered KBO's see the related link

How did scientists make and accept that Pluto was no longer a planet?

They realized that Pluto was in fact a member of another belt of objects orbiting the sun, similar to the asteroid belt. The same thing happened with four of the asteroids in the asteroid belt. Once scientists realized that they were just four of hundreds of thousands of objects sharing the same orbit, they no longer considered them planets. Pluto is a member of a similar belt of objects known as the Kuiper Belt.

Is the sun Terrestrial or a gas planet?

The sun is classified as a star, not a planet. It is a massive ball of hot gas primarily composed of hydrogen and helium.

What planet is considered the dwarf planet?

Dwarf planets are objects in our solar system that are big enough to pull themselves into a rounded shape yet orbit the Sun in a "messy" neighbourhood (like the asteroid belt, or the Kuiper Belt beyond Neptune.) So far, the International Astronomical Union lists five dwarf planets: Ceres in the asteroid belt, and Pluto, Haumea, Makemake and Eris in the Kuiper Belt. However, it is highly likely that a LOT more objects out there in the Kuiper Belt are round and therefore dwarf planets - we just haven't been able to observe them closely enough to prove it. It's likely that by the time we have better pictures of everything we've discovered so far we'll have found dozens, perhaps even hundreds of dwarf planets out there. Some examples of things that are almost certainly dwarf planets but that the IAU doesn't list yet as their shape isn't proven are Ixion, Orcus, Varuna, Quaoar and Sedna. So bear in mind that any list of dwarf planets is bound to grow quickly and will be out of date soon!

If you believe dwarf planets are planets, you can remember the five dwarf planets in order from the sun with the mnemonic: "Can Planets Have Massive Eccentricity?"

If you don't believe dwarf planets are planets and that only the eight big ones count, you can use this one: "Counting Planets Here Means Eight!"

And if you want to remember the five dwarf planets alongside the eight other planets, use "My Very Easy Method Can't Just Speed Up Naming Planets, However Many Exist!"

Before planets were planets what were they?

they were lumps of rock floating in space. then they were pull into a gravitational pull and then they evolved. and produced life forms which then evolved into humans , we are only hear through scientific development NOT because of GOD! :)

A meteriod with a diameter of 1cm strikes the Moon What will the crater diameter be?

That would depend on several factors; the velocity of the meteoroid, the mass, density and composition of the meteoroid, and the nature of the surface where it strikes.

Is Jupiter a gas planet or terrestrial planet?

Jupiter is a gas planet, primarily composed of hydrogen and helium. It does not have a solid surface like terrestrial planets such as Earth.
