100

It is the name of the first European astronomer to propose the heliocentric model.

Nicolaus Copernicus

100

this is the outermost layer, with a temperature of about 500,000 °C or more.

Corona

100

The moon is approximately 3,476 km in diameter, or a quarter of the size of the earth

size

100

It can shift between annular and total eclipse.

Hybrid solar eclipse

100

It is the star, which is 93 million miles away from the planet earth

Sun

200

This model states that earth is the center of the solar system.

Geocentric model

200

this is above the solar surface, and is the only layer that can be seen during a solar eclipse.

Chromosphere

200

The moon’s atmosphere is very thin. It is so thin that it doesn’t have oxygen available to breathe

Atmosphere

200

The moon appears small, so it looks like a dark disc on top of the sun.

Annular eclipse

200

It is the closest planet to the sun.

Mercury

300

This model states that the sun is the center of the solar system

Heliocentric model

300

this is the layer that we can observe directly, and it is mostly covered by granulation.

Photosphere

300

The causes of the depressions on the surface is the millions of years of rocks hitting the surface of the moon. Some volcanoes also contributed to create the craters of the moon.

Craters

300

The sun, the moon and the earth are not perfectly aligned, so only part of the sun is covered.

Partial eclipse

300

It is the warmest planet of the solar system.

Venus

400

It is the attraction force that pulls everything you can touch.

Gravity

400

this is one of the inner layers, where energy moves towards the surface through convection streams of heated and cooled gas.

convection zone

400

The moon is about 384,000 km away from earth

Distance

400

Whenever the moon is not totally blocking the sun.

Non-total eclipse

400

It is famous because of its rings.

Saturn

500

It is the planet where we live.

Earth
500

this is where energy is born by thermonuclear reactions and this creates extreme temperatures.

Core

500

During the day the moon is 107° degrees Celsius while at night it drops to -153 degrees Celsius.

Temperature

500

This type of eclipse happens when the moon completely blocks the sun from the earth’s surface.

Total eclipse

500

It is the coldest planet in our solar system.
