Top 5 Astronomy Misconceptions

Hey guys, this is Astronomical Thoughts where
i discuss really cool ways of thinking about astronomy phenomena. and in this video, i’m going to be discussing
5 common misconceptions people have about astronomy. In this video, I have left out some misconceptions
that I have already discussed in videos such as what causes the season and what color is
the sun. So please check these videos out if you are
interested. ok so 1st misconception: shooting stars are
stars dying. So, shooting stars are not actually stars, they are just debris or small rocks falling
through the earth’s atmosphere. most of these small rocks get burnt in the
atmosphere but some hit the ground which we call meteroits. 2nd misconception: planets orbit in perfect
circles. So, planets’ orbits are not circular but rather
elliptical. 3rd misconception: Mercury is the hottest
planet in the solar system. Because mercury is the closest planet to the
sun, people think that the whole planet must be really hot. But that’s not the case. because mercury does not have an atmosphere,
it cannot keep or trap its heat, so the surface facing the sun is super hot while the surface
facing away from the sun is super cold, in fact the side facing away from the sun
is colder than the planet mars. And just in case, you were wondering what
the hottest planet in the solar system is, it’s venus which is the second closest planet
to the sun. And the
reason why venus is the hottest planet in the solar system is because venus has a really
thick atmosphere so all the heat coming from the sun gets
trapped inside making the planet hotter and hotter. 4th misconception: all planets have moons. Mercury and venus do not have moons. The reason for this is because mercury and
venus are too close to the sun. For example,
let’s say that mercury had a moon, now if that moon was a bit too close to the sun,
that moon would just get captured by the sun and
if the moon was a bit too close to mercury, then the moon would just smash into mercury. So it would be very difficult for the moon
to find a good position to orbit for a planet that is so close to the sun. And the same logic goes for the planet venus
as well and why it doesn’t have moons. 5th misconception: we can only see the moon
at night. This is completely false. Our Moon is sometimes visible during the day. it’s just that during the day, the sunlight
is so much that it overshadows the moonlight making it difficult for us to see the moon. Thanks for watching, take care and see you
guys in the next video.
