how many planets are there and what are the names of them?

Question

10 points for best answer-i keep getting mixed up on what they are. can you please help me? thanks

Answer 1

8 planets:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
9 if you are counting Pluto, which is a dwarf planet.

Answer 2

The solar system consists of the Sun; the eight official planets, at least three "dwarf planets", more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. (There are probably also many more planetary satellites that have not yet been discovered.)

The inner solar system contains the Sun, Mercury, Venus, Earth and Mars:



The main asteroid belt lies between the orbits of Mars and Jupiter. The planets of the outer solar system are Jupiter, Saturn, Uranus, and Neptune (Pluto is now classified as a dwarf planet):


One way to help visualize the relative sizes in the solar system is to imagine a model in which everything is reduced in size by a factor of a billion. Then the model Earth would be about 1.3 cm in diameter (the size of a grape). The Moon would be about 30 cm (about a foot) from the Earth. The Sun would be 1.5 meters in diameter (about the height of a man) and 150 meters (about a city block) from the Earth. Jupiter would be 15 cm in diameter (the size of a large grapefruit) and 5 blocks away from the Sun. Saturn (the size of an orange) would be 10 blocks away; Uranus and Neptune (lemons) 20 and 30 blocks away. A human on this scale would be the size of an atom but the nearest star would be over 40000 km away.

Answer 3

As i read from my book there are 200+ exoplanets or planets here in our solar system discovered... Name of the planets: Solar system planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune, Uranus and SEDNA the new planet here in our solar system, Pluto is not included because it is now called a dwarf... Exoplanets:
HAT-P-1
HD149026b
Corot-Exo1b-en
Corot-exo-1b
Corot-exo-1
HD 189733
HD 189733b
HD 43691b
HD 132406
HD 74156
HD 37605

Sorry i cant name the others... OK Tnx..

Answer 4

NASA has discovered 169 moons in our Solar System and our Milky Way Galaxy has cannabilized smaller galaxies, for a total of 235+ planetary bodies/moons. We should be building restaurants all over the Milky Way Galaxy. Callisto, Io, Ganymede and Europa are just some of the satellite moons that have been named.

Venus=0, Earth=1, Mars=2, Jupiter=63, Saturn=60, Uranus=27, Neptune=13, Pluto=3

Here's how it would work: We'd drill a shaft halfway down the center of the planet/moon and insert a Superconducting Ring that is cryogenically sealed in liquid helium, (much like an MRI machine and there are several companies which specialize in this technology). The Superconducting Ring would range from 4 to 14 Tesla, depending on the amount of iron/nickel resident in the core. Once the Superconducting Ring is supercooled to transition into a superconducting state, a permanent magnet is used to induce a current. This current is said to "persist" forever. Using a magnetometer, you'd measure the magnetic field at a given point on the surface of the globe, if it's within 0.5 to 2.0 Gauss, it's a viable atmospheric bubble. Next, pump in nitrogen, oxygen and co2 and bring grass seeds and voila, an atmosphere.

Another approach is to create/enhance the internal "Dynamo" in a globe which spins on its axis. If the globe is geologically active, it might have a light atmosphere owing to the "eddy currents" arising from the spinning of molten iron/nickel in the core. This creates the surface gravity which holds the atmosphere to a planet. To increase the surface gravity, you would have to drill a shaft halfway down the center of the globe and pour molten iron/nickel down the shaft, and add some radioactive element like polonium to keep it molten forever. Once the magnetic field strength at a point on the surface of the globe is 0.5 to 2.0 Gauss, it's a viable atmospheric bubble capable of holding down life sustaining gases like nitrogen, oxygen and CO2.

Answer 5

According to IAU: International Astronomical Union, there 8 planets in the solar system.
Mercury, Venus, Earth, mars, Jupiter, Saturn, Uranus and Neptune.

There are also 3 planetoids. These have met all conditions to be a planet except two. They are either not massive (in size speaking) or have not cleared their orbit of other objects These include:
Pluto, Ceres and Eris. Sedna will soon get added to them probably. There are yet many to be found out in the Kuiper belt.

Answer 6

Besides the 8 main planets and 3 dwarf planets, there are several other planets that have been discovered around other stars as well.

Answer 7

8 planets
mercery
venus
eartH
mars
jupiter
saturn
uranus
neptue


PLUTO IS A PLUTOID

Answer 8

Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune

They excluded Pluto, but for me it will be always the 9th planet, check-out this website, it's pretty cool

Answer 9

We don't know how many there are. And most outside of our own galaxy have numbers/letters, and not names.

Answer 10

8
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune

And 3 dwarf planets:
Ceres
Eris
Pluto
