<span>There are typically two
planets that are dubbed as Earth's twin. The first one, Venus, is called
Earth's twin because of its similar size, and how it is the closest
planet to Earth. But, scientists discovered that Venus's atmosphere and
temperature were totally different from Earth's. The other planet also
called Earth's twin is Mars. Mars is believed to have a large ocean on
the past. Some even say that life may have developed on Mars for a short
period of time. Furthermore, Mars has an average temperature of -70
degrees Fahrenheit, closest to Earth than any other planet. It seems that
water and life define the Earth, and if Mars has these characteristics,
it would truly be Earth's twin.
P.S
Have an AWESOME!! day :)
