Yes.
Especially if you are overweight, you may just think its from eating that piece of Pizza when in reality you are 8 months pregnant.
A friend of mine went through her entire pregnancy unaware that she was pregnant! then she went into labor went to the hospital and had her baby!
Rocky planets
Unknown, but there would be no "soil" no matter what the core consists of - presumably rock and iron.
The first five planets in the order from closest to farthest are Mercury, Venus, Earth, Mars, and Jupiter. The first four planets are inner planets, and Jupiter is an outer planet.
The inner planets are typically warmer than the outer planets. This is because the inner planets are closer to the sun and receive more direct sunlight, leading to higher temperatures. In contrast, the outer planets are much farther from the sun and are colder as a result.
Planets, exoplanets, asteroids. They're all sattelites of the sun.
It is Unknown
Scientists predict that they are planets because there wouldn't be random gas' from unknown places
Currently there are 353 known extrasolar planets (that is to say, outside of our solar system), but it is unknown how many planets exist in the universe.
If you refer to creatures from other planets, that is currently unknown.
yes, but as for how many... no one knows since they are unknown lol I hope I answered your question!
Pluto and the unknown planet Falkite (falk-i-tee)
It's easier to ask how many were known, and the answer is six.
If you are asking about "space aliens", as in "lifeforms from other planets", the only honest answer is "Unknown."
that informations is unknown. But hey a guy can dream
It's unknown. We didn't discover a planet with water, and oxygen.
Extraterrestrial are unknown humans. They are humans, but different kinds from different planets. Like aliens and UFOs. The scientific community think this is true. They think they come from planets beyond Earth...
scientists are studying about life on mars, but unfortunately it is still unknown! there is still no life on other planets.
