BY TODAY HOW MANY PLANETS ARE IN OUR SOLAR SYSTEM?????

Question

I heard NASA or some telescope in San Deigo discovered a new planet. I want to know how many big planets we have and how many small ones now. Also i want to know how many new planets they discover in our solar system.

Answer 1

There are only eight planets now that Pluto is still being referred as a dwarf planet.  

Answer 2

10!!!Ten last is called SEDNA!!

Answer 3

There are only eight planets since they kicked Pluto out. But there are many moons and several of what I think they are calling Plutoids, which are too small to be planets, but too large to be asteroids.

Answer 4

9

Answer 5

mercury

venus

earth

mars

ceres (in aseroid belt)

jupitar

saturn

uranus

neptune

sedna

10 planets

Answer 6

According to the IAU's current definitions, there are eight planets in the Solar System. In increasing distance from the Sun, they are:

Mercury

Venus

Earth

Mars

Jupiter

Saturn

Uranus

Neptune

Jupiter is the largest, at 318 Earth masses, while Mercury is smallest, at 0.055 Earth masses.

The planets of the Solar System can be divided into categories based on their composition:

Terrestrials: Planets that are similar to Earth, with bodies largely composed of rock: Mercury, Venus, Earth and Mars.

Gas giants: Planets with a composition largely made up of gaseous material and are significantly more massive than terrestrials: Jupiter, Saturn, Uranus, Neptune. Ice giants, comprising Uranus and Neptune, are a sub-class of gas giants, distinguished from gas giants by their significantly lower mass, and by depletion in hydrogen and helium in their atmospheres together with a significantly higher proportion of rock and ice.

Before the August 2006 decision, several objects were proposed by astronomers, including at one stage by the IAU, as planets. However in 2006 several of these objects were reclassified as dwarf planets, objects distinct from planets. Currently four dwarf planets in the Solar System are recognized by the IAU: Ceres, Pluto, Makemake and Eris. Several other objects in both the Asteroid belt and the Kuiper belt are under consideration, with as many as 50 that could eventually qualify. There may be as many as 200 that could be discovered once the Kuiper belt has been fully explored. Dwarf planets share many of the same characteristics as planets, although notable differences remain – namely that they are not dominant in their orbits

Extrasolar planets

The first confirmed discovery of an extrasolar planet orbiting an ordinary main-sequence star occurred on 6 October 1995, when Michel Mayor and Didier Queloz of the University of Geneva announced the detection of an exoplanet around 51 Pegasi.

Of the 306 extrasolar planets discovered by August 2008, most have masses which are comparable to or larger than Jupiter's, though masses ranging from just below that of Mercury to many times Jupiter's mass have been observed.

The smallest extrasolar planets found to date have been discovered orbiting burned-out star remnants called pulsars, such as PSR B1257+12. There have been roughly a dozen extrasolar planets found of between 10 and 20 Earth masses, such as those orbiting the stars Mu Arae, 55 Cancri and GJ 436

Answer 7

8 since pluto got the boot.

Mercury

Venus

Earth

Mars

Jupiter

Saturn

Uranus

Neptune

pluto is no longer a planet.  it is now considered a dwarf planet.

sedna is also not considered a planet, that is a dwarf planet too.

Answer 8

Mercury

Venus

Earth

Mars

Jupiter

Saturn

Uranus

Neptune

Pluto

Sedna

Sedna was discovered in 2006- Search it up

Answer 9

Now no more planets r 2 b added in the solar system until IAU permits. So, there are 8 planets.

Answer 10

Eight Planets and THREE dwarf planets--

Answer 11

There are only 8 planets.

Answer 12

This new dwarf planets were all really close to being a planet, as it now isn't. Right now the are 8. They are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The largest object in the Solar System is Jupiter, being followed by Saturn, Uranus, Neptune, Earth, Mars, and Mercury in that order. The dwarf planets are all after Mercury as their largest-to-smallest order is Eris, Pluto, Makemake, EL61, Sedna, Orcus, Quaoar, and finally Varuna. So they haven't discovered any new planets, but 7 dwarf planets.

Answer 13

SUCH a simple question, and yet so many wrong answers.  Scary.

The correct answer is 8 full planets.

Answer 14

10 if you count pluto and nibiru.

Answer 15

There are eight.

We have 4 big ones and 4 smaller ones.

Earth is considered as a small one.

They've discovered a planet called Planet X that is affecting our pole shifts and possibly will bring the world to an end.  

Answer 16

8.
