Jupiter is the biggest planet.Jupiter est la plus grosse planète.
Venus is the hottest planet.Vénus est la planète la plus chaude.
Mercury is the closest to the Sun.Mercure est la plus proche du Soleil.
Neptune is the farthest from the Sun.Neptune est la plus éloignée du Soleil.
Saturn is less dense than water.Saturne est moins dense que l'eau.

Mercure est la plus proche du Soleil, mais ce n'est pas la plus chaude : c'est Vénus (plus de 450 °C), à cause de son atmosphère épaisse qui piège la chaleur. Jupiter est la plus grosse : plus de 1 300 Terres pourraient y tenir ! Neptune est la plus éloignée. Comparatif des adjectifs courts : -er than (bigger than) ; superlatif : the -est (the biggest). Attention : hot → hotter, big → bigger (consonne doublée).
