Hello everyone and welcome to our outer space adventure! On this journey, we'll get to explore the solar system and learn about the planets - including the one we call home. Let's suit up, our mission of planetary exploration begins now!

To do that, we will use this spacecraft to travel to the solar system. Come on let's go!

  To begin with, I would like to introduce the huge sphere in front of us, which is the Sun. The Sun is the planet at the center of the solar system that accounts for 99.8% of the mass of the solar system and is surrounded by celestial bodies such as Earth, planets, asteroids, meteorites, comets,...    

The average distance between the Sun and Earth is approximately 149.6 million kilometers, so sunlight takes 8 minutes and 20 seconds to reach Earth. The average diameter of the Sun is 109 times larger and 332,946 times heavier than Earth. 

 The composition of the Sun includes hydrogen, helium, iron, nickel, oxygen, silicon, sulfur, magnesium, carbon, neon, calcium and chromium. The surface temperature of the Sun is approximately 5505 celcius degrees. Because the temperature is so high, we cannot get close to the Sun or we will burn. So we're currently outside the orbit of Mercury. 

The next planet we will discuss is Mercury, the smallest planet in our solar system and closest to the Sun. Orbiting with an extremely fast period of 88 Earth days, Mercury resides just 58 million kilometers from the solar star. Slightly larger than Earth's lone moon, Mercury is only slightly larger in size yet experiences extreme surface temperatures due to its proximity to the life-giving star.

As a terrestrial planet composed of rocky materials, Mercury has a heavily cratered surface similar in appearance to our lunar neighbor. Without a significant atmosphere to regulate it, the temperature on Mercury varies wildly from a high of 430 Celsius degree during the day to a frigid -180 degrees at night. Along with its compacted structure and lack of satellites, Mercury's rapidly alternating temperature extremes are largely the result of its small size and circular path around the Sun in just 59 Earth days, with a year that lasts only 88 days on our home world.

Orbiting swiftly as the smallest world in our solar neighborhood and facing volatile weather without an atmosphere, Mercury provides insights into the advancement of planetary formation near our star's immense heat and light.

The second planet from the Sun is Venus, similar in size and mass to Earth but with vastly different climatic conditions. Rotating backward in the opposite direction to Earth once every 243 days, Venus orbits the Sun every 224.7 days. With a thick, cloud-shrouded atmosphere composed primarily of carbon dioxide, Venus is enveloped in dense, highly reflective sulfuric acid clouds that drive surface temperatures to an average of a scorching 462°C.

As the hottest planet in the solar system, Venus lacks liquid surface water due to atmospheric pressure 92 times greater than Earth's. Its runaway greenhouse effect is intensified by the dense carbon dioxide producing a dry, desert-like landscape across its entirely terrestrial, volcanic rocky terrain. Beneath a shroud of reflective clouds thicker than any planet, Venus spins so slowly that its days last longer than its years.

Atmospheric properties and the intense greenhouse effect make Venus' surface inhospitable despite similarities in composition, size and mass shared with Earth.

On to the next, the third planet in the solar system is our home,  Earth. Our home is the third planet from the Sun and the largest of the terrestrial planets of the solar system in terms of radius, mass, and density of matter.

Orbit and cycle: Earth orbits the Sun at about 107,000 km/h. Every day on Earth is 24 hours long and each year is as long as 365.24 days.

Location and size: Earth is the third planet from the Sun. The diameter at the Earth's equator is 12756 km.

Structure and surface: Earth is a rocky planet. 70% of the Earth's surface is water.

Atmosphere: Earth's atmosphere is up to 10,000km wide. The composition of the atmosphere is mostly nitrogen (Noxygen (O2), and other gases.

Temperature: Earth's average surface temperature is 13.85 degrees Celsius. But because of the greenhouse effect, Earth's average temperature has recently increased. According to the National Oceanic and Atmospheric Administration, the average temperature of the Earth reaches a high of 17.18 degrees Celsius.

Satellite: Earth has a natural satellite, the Moon.

Let's fly to the fourth planet in the solar system, Mars.

Orbit and period: Mars has orbital period of about 686,980 Earth days. A day on Mars is 24 hours and 37 minutes long.

Position and size: Mars is the fourth planet from the Sun. It is half the size of the Earth.

Structure and surface: Mars is a rocky planet. Its surface is reddish-orange due to being covered with iron (III) oxide crumbs.

Atmosphere: Mars' atmosphere is quite thin with carbon dioxide as its main component. Atmospheric pressure at the planet's surface is 0.636 kPa.

Temperature: Mars' average maximum and minimum surface temperatures are -143.15 degrees Celsius, -63.15 degrees Celsius, and 34.85 degrees Celsius.

Satellites: Mars has two natural satellites, Phobos and Deimos.
