Which are the new planets?

Answer 1

There are several satellite projects searching for new extra solar planets, and discoveries are being made every month. Since all of the stars that these planets orbit have a catalog designation or a name of their own, the new planets are being given a letter (starting with b, then c.) to follow the name or number of the star. The discoveries of new planets by satellite projects are being give the name of that project, but still only a letter after the satellite project's name. example: COROT 1 b.

In our own solar system, there are four new dwarf planets:

#5 - Ceres

#11 - Haumea

#12 - Makemake

#13 - Eris.

Answer 2

As of now, the planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There have been no new planets discovered within our solar system in recent times. However, astronomers continue to search for exoplanets outside our solar system.

Answer 3

One new planet found is Gilese 581g, which orbits in the constellation Libra. It is about 20 light-years away. It is thought to be capable of harboring water, and thus life. It is about three to four times the mass of Earth.

Gliese 581g (whose first name is pronounced GLEE-za) circles a dim red star known as Gliese 581, once every 37 days, at a distance of about 14 million miles. That is smack in the middle of the so-called Goldilocks zone, where the heat from the star is neither too cold nor too hot for water to exist in liquid form on its surface.

Five other new planets were found this year (2010). They are referred to as "hot Jupiters". They are about the same mass as Jupiter and orbit very close to their stars. They have been called Kepler 4b, 5b, 6b, 7b, and 8b, and range in temperature from 2,000 to 3,000 degrees Fahrenheit (1,090 to 1,650 degrees Celsius).

Answer 4

A newly discovered planet is eerily similar to Earth and is sitting outside Earth's solar system in what seems to be the ideal place for life, except for one hitch. It is a bit too big. The planet is smack in the middle of what astronomers call the Goldilocks zone, that hard to find place that is not too hot, not too cold, where water, which is essential for life, does not freeze or boil. And it has a shopping mall-like surface temperature of near 72 degrees, scientists say.

Answer 5

Presumably, somewhere in the universe, there are new planets.

Around here, in our Solar System? No there aren't. They're all billions of years old, and even if you're just using "new" in the sense of "newly discovered" it's been a few hundred years since we found the last one.

We are more or less constantly finding planets in othersolar systems. If that's what you meant, then yes, there are lots of new ones.

Answer 6

"The new planet" is ambiguous. New exoplanets are being discovered all the time. The current "hot" news as of January 2012 is the Kepler experiment, which is able to detect smaller planets than has previously been possible, and the planets discovered with it are getting number-names of the form "Kepler-1".

Answer 7

Over 400 planets have been discovered so far around other stars.

Answer 8

For the planets accepted by the International Astronomocal Union in our planetary system the list is complete; Sedna, discovered 10 years ago is considered only a dwarf planet, as Pluto.

Answer 9

Yes. Recently, 32 planets have been discovered outside Earth's solar system through the use of a high-precision instrument installed at a Chilean telescope site.

Answer 10

New planets are discovered every few days.
