Fly me to the moon

Here you want to write a short paragraph that quickly explains exactly what your online course is and how it’s the perfect solution to the problems you’ve been talking about in the previous section. Keep it short, but provide the essential information they need to be able to make sense of what’s coming. For example, make sure they know that it is an online course designed to teach them how to achieve their goal

The Moon is Earth’s only proper natural satellite. At one-quarter the diameter of Earth (comparable to the width of Australia),[13] it is the largest natural satellite in the Solar System relative to the size of its planet, and the fifth largest satellite in the Solar System overall (larger than any dwarf planet). Orbiting Earth at an average lunar distance of 384,400 km (238,900 mi),[14] or about 30 times Earth’s diameter, its gravitational influence is the main driver of Earth’s tides and slightly lengthens Earth’s day. The Moon is classified as a planetary-mass object and a differentiated rocky body, and lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth’s (0.1654 g); Jupiter’s moon Io is the only satellite in the Solar System known to have a higher surface gravity and density.
