- from Mars
If Earth is the “third rock from the sun,” then Mars is number four. All four inner planets – Mercury, Venus, Earth, and Mars – are made of rock.
Of course, they look more like pebbles next to the four “gas giants” – Jupiter, Saturn, Uranus, and Neptune.
If you’re planning a vacation to some spot in the solar system, Mars is definitely your best bet. After all, it’s right next door – only a seven-month trip away! It also happens to be the most livable planet after Earth – apart from the lack of air, food, and water! Plus, the summer season lasts six months – twice as long as Earth’s. Some summer days, the temperature rises just above the freezing point, and sometimes it reaches 70°F!
