(3) What is the situation of the planet?
(4) What did you do in space? Did you have a spacewalk or collect any samples?

Tips 2.The information about nine planets in solar system
Mercury is the closest planet to the Sun and the eighth largest. In Roman mythology Mercury is the god of commerce, travel and thievery.Temperature changes so extremely and it varies betweent90 K and 700 K. It has no known satellites
Venus is the second planet from the Sun and the sixth largest. Venus' orbit is the most nearly circular of that of any planet, with an eccentricity of less than 1%. Venus is sometimes regarded as Earth's sister planet. In some ways they are very similar.Venus has no satellites.
Earth is the third planet from the Sun and the fifth largest. It is our mother planet. Three forth of the surface covers water. Earth has only one natural satellite, the Moon. But thousands of small artificial satellites have also been placed in orbit around the Earth
Mars is the fourth planet from the Sun and the seventh largest. Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red color. It is considered to be the most suitable planet which human can live on. The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including Mars 2. It has two satellites
Jupiter is the fifth planet from the Sun and by far the largest. Jupiter is more than twice as massive as all the other planets combined (the mass of Jupiter is 318 times that of Earth).Jupiter is the fourth brightest object in the sky (after the Sun, the Moon and Venus).
Saturn is the sixth planet from the Sun and the second largest: It has three prominent which can be seen from the Earth and it has 34 named satellites.
Uranus is the seventh planet from the Sun and the third largest (by diameter). Uranus is larger in diameter but smaller in mass than Neptune.It looks blue. Uranus has 21 named moons and six unnamed ones:
Neptune is the eighth planet from the Sun and the fourth largest (by diameter). Neptune is smaller in diameter but larger in mass than Uranus. In Roman mythology Neptune (Greek: Poseidon) was the god of the Sea.Neptune has been visited by only one spacecraft, Voyager 2 on Aug 25 1989.
Pluto orbits beyond the orbit of Neptune (usually). It is much smaller than any of the official planets and now classified as a "dwarf planet". Pluto is smaller than seven of the solar system's moons. In Roman mythology, Pluto (Greek: Hades) is the god of the underworld. Pluto has not yet been visited by a spacecraft. .but we have found that is has a satellite.
Tips3. One possible version
Good morning, boys and girls. I’m so glad to be here to tell you something about my journey. I had a space travel to Venus last month by Shenzhou Ⅷ, which was launched with two rockets.
Venus is the second planet from the Sun and the sixth largest. Its orbit is the most nearly circular of that of any planet, with an eccentricity of less than 1%. Venus is sometimes regarded as Earth's sister planet. In some ways they are very similar. It has no satellites.
My partner and I had a space walk everyday and we collected lots of samples. We often stayed in the space station and took photos of the planet. We didn’t find any alien and other creature on Venus.
In our spare time, we also listened to the music, played computer games and talked with our family through the telephone. We enjoyed the lives there.
Space exploration is interesting and I wish you will enjoy it one day. Thank you for listening
