Our solar system is made of 8 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune! Each planet orbits around the Sun. The closest planets to Earth are Venus and Mars. In the Bible, sometimes the HOSTS of the heavens refers to the planets and stars in the sky!
[6] By the word of the Lord the heavens were made, and by the breath of his mouth all their host.
- - Psalms 33:6 (NASB)
