- 16. is the first planet in our solar system and the smallest one. It has a solid surface that is covered with craters. It has no atmosphere, and it doesn't have any moons.
- 20. It is an M-Type asteroid, its orbit period it’s about five Earth years. There is going to be a mission with the main purpose of investigating this asteroid.
- 22. is the first mission to collect a sample of the near-Earth asteroid 101955 Bennu.
- 23. solar probe this is a scientific mission to investigate the mysteries of the Sun’s corona and solar wind.
- 26. it was discovered in June,26 of 2014. It is the most distant object visited by a spacecraft. Is the reddest outer solar system object visited by a spacecraft.
- 27. 2 This is a comet with the shape of a flattened sphere, it is known as a fresh periodic comet.
- 29. Is a dwarf planet and is the farthest planet from the sun. The surface of this planet is covered with ices, and has mountain ranges, light and dark regions, and craters.
Down
- 1. It is located in the Kuiper Belt, it's really cold and it is the second brightest icy dwarf planet.
- 3. is the sixth planet in our solar system and the second largest planet. It is a gas giant planet made up mostly of helium and hydrogen and it has thousands of beautiful ringlets.
- 4. Is the eight planet in our solar system. Is an ice giant and it is made of a thick soup of water, ammonia, and methane flowing over a solid core.
- 6. is the second planet in our solar system. The surface of this planet is extremely dry and is the hottest planet in the solar system.
- 9. Is the fourth planet in our solar system and is the second smallest planet. This planet is also named as the “Red Planet”. It is a terrestrial planet with a thin atmosphere.
- 10. they build up a spacecraft created to perform a detailed study of this comet, the spacecraft is called Rosetta. This comet was first observed in 1969.
- 12. behind it provided scientists a unique and revolutionary view of the Sun- Earth system. In 2014 NASA operations lost contact with the spacecraft.
- 13. this dwarf planet is a geologically active body also this planet has less than a third of the moon’s width.
- 17. 10 It was NASA’s first mission to the outer planets. It was the first spacecraft to visit Jupiter, the first one to fly beyond Mars, the first one to fly through the main asteroid belt, it was the first human-made object to go beyond Neptune.
- 18. Is a natural satellite of Pluto and is the third farthest moon from Pluto. Is the third largest moon.
- 19. 1 it's a short-period comet and it has made many passages through the inner solar system. Also, it was the ninth periodic comet to be recognized as one.
- 21. Is the largest moon of Pluto. Is so big that Pluto and this moon orbit each other. This moon has a frigid surface, covered with nitrogen ice, methane and possibly some water ice.
- 24. this asteroid was discovered on Aug,13,1898. This asteroid is known for being the first asteroid to be orbited by a spacecraft.
