Of course! Where we are now in space science is only the tip of the iceberg. There are so many unknown things out there.
Additionally
Astronomers are just discovering new planets outside our solar system. Until recently the planets were too far away and too dim to be seen by our best telescopes.
There were 6 known planets, Uranus and Neptune weren't discovered yet.
No, all land on Earth has been explored. However not all areas of the Ocean have been explored because we are not advanced enough in technology to go as deep as the Ocean floor is in some parts of the Ocean.
ellipses.
The extrasolar planets discovered so far most resemble those in our own solar system, including rocky planets, ice giants, and gas giants. However, there is a wide variety of exoplanets with unique characteristics that differ from those we find in our solar system.
Kepler discovered that the planets orbit the sun in oval shaped paths called ellipses.
i only know two planets the to planets are pegasus 51b and the niburu
No. We know what the stars are. They are not planets. They are distant suns, many of which do have undiscovered planets.
There may be ice on some planets that we haven't discovered yet. However, there is ice on Mars and once believed for there to be water.
There were 6 known planets, Uranus and Neptune weren't discovered yet.
Not yet, but, as we have discovered water on various planets and moon, the possibility of life - as we know it - does exist.
No, all land on Earth has been explored. However not all areas of the Ocean have been explored because we are not advanced enough in technology to go as deep as the Ocean floor is in some parts of the Ocean.
Science hasn't yet discovered which planets house extra-terrestrials neither have they assigned names to them.
Yes, but not all. Some planets either evolved without an atmosphere or had their atmosphere decimated by solar wind or gamma-ray bursts. If you are asking are there other habitable planets in the universe - then absolutely. We've not discovered them yet, but there are probably billions, if not trillions of habitable planets elsehwere in the universe, waiting to be discovered.
The same planets that orbit today, though Uranus and Neptune had yet to be discovered, along with Pluto (now regarded as a Dwarf Planet).
Well 8 known planets!! Pluto is not considered a planet now. There is a new "planet" discovered but it is not a "planet" yet!! Itvis called Kepler16B
NO! well not what scientists has discovered yet
No, with modern technology, in most cases only planets that are relatively nearby can be discovered.
