Why is it so hard for astronemers to learn about mercury?

Answer 1

Mercury is the closest planet to the Sun, and MUCH closer to the SUN than the Earth so whenever we (astronomers or anyone from Earth) observe Mercury, we are looking almost directly at the Sun.

Even when the Sun is not behind Mercury (from our perspective), we are still looking through all the light, radiation, and electromagnetic interference between the Earth and Mercury. This makes observing Mercury very hard, even with the latest in technology, because the interference is intense due to Mercury's close proximity to the Sun.

The only way to get accurate readings (free from the Sun's interference) is to put a satellite in orbit around Mercury. This was finally accomplished in 2011 when the MESSENGER satellite began mapping the surface of Mercury.

Answer 2

planet mercury is so small because while our solar system was forming, there were 100s of planets. This eventually turned into a demolition derby of some sort. During all of this, a large planet crashed into Mercury, blasting off most of the planet, leaving only its core. So the Mercury we see today is actually the core of Mercury.

Answer 3

it is because Mercury is so close to the sun so if an astronomer looked at Mercury they would be blinded by the sun and an astronaut cant land on mercury because its to hot and mercury is made out of liquid

Answer 4

Being the innermost planet, it is very close to the sun and so is visible only near sunrise and sunset when the sky is often still light. It is very difficult to see it against the sun's bright disk.

Answer 5

Astronomers have difficulty studying Mercury due to its proximity to the Sun, which makes it challenging to observe against the bright background. Additionally, Mercury's thin atmosphere and lack of geological activity limit the amount of data astronomers can gather about the planet's composition and surface features.

Answer 6

Recently, Pluto is categorized as a dwarf planet. Hence, Mercury became the smallest planet now.

Answer 7

because its to close to the sun

Answer 8

It has no significant atmosphere.
