Can we thrive on other planets in the universe?
On another planet 在另一个世界
Earth is part of the solar system. Our sun's core provides the power. It is surrounded by eight planets: Mercury, Venus, Earth, Mars, Jupiter, Neptune, Uranus and Saturn. Pluto lost its planet status in 2006 and is now considered to be a dwarf planet.
地球是太阳系的一部分。太阳的核心是整个太阳系动力的源泉。八大行星围绕着太阳，分别是：水星，金星，地球，火星，木星，海王星，天王星和土星。在2006年冥王星失去了行星的地位，现在被认为是矮行星。
如果形容一个人是在另一个世界，那就表示这个人对眼前的事情心不在焉，漠不关心。
例句
Jane's on another planet – she went to buy some apples and bought lemons instead!

请注意
如果说一个人 living on another planet 那么意思就是说这个人一点都不现实。
例句
He thinks we'll be able to drive to Paris by tonight – he's really on another planet!
If she thinks we can afford a two-week holiday in Spain she's living on another planet!
