Using the highest estimates on the mass of the Oort cloud, the total mass of the solar system, excluding the Sun itself, is about 30 Jupiter masses. Mirages work in the desert because hot air has a different refractive light index than cold air. Though the Parker Solar Probe has already offered a glimpse into the sun's atmosphere, its work isn't done yet. The government kept the information classified which meant, of course, the public would not be made aware of any such discovery. While scientists at NASA were rejoicing in their new discoveries, three Americans and three Russians were exploring our sister world dressed not in space suits, but as casually as any hunter in the woods here on Earth.
