👉🌌The Hubble Space Telescope has traveled more than 4 billion miles since its launch in 1990 — an amazing distance for a spacecraft that never leaves Earth’s orbit. Hubble circles our planet at an altitude of about 340 miles (550 km). It completes one full orbit roughly every 95 minutes, which means it goes around Earth about 15 times each day. Moving at nearly 17,000 miles per hour (27,000 km/h), these constant high-speed laps have added up to billions of miles over the years. However, Hubble
