The Space Doctor on Instagram: "Watch till the end. Stay behind me queen. Evidence from astronomical models and simulations suggests that Uranus's orbit was unstable in the early solar system. Jupiter and Saturn indeed played a major role in making Uranus’s orbit unstable during the early history of the Solar System. This instability is explained through a process known as the Nice Model. When Jupiter and Saturn got locked in a 2:1 resonance they destabilized the outer solar system and at one po

This presentation worked great for the likes of @chuckliddell @basruttenmma and some others. The key to this for street combatives is to plant your feet and align your lead and rear hands. Basically loading your body while keeping options on which strike you will deliver! Now of course we would rather not punch in the street so just open your

BOS Planet on Instagram: "☄️ 3I Atlas just flew past Mars—And it’s getting closer! 3I/ATLAS, only the third interstellar visitor ever spotted in our Solar System. It swung closest to Mars on October 3, 2025 (~29 million km from Mars) and is racing toward the Sun for perihelion around October 29–30 (≈ 1.36–1.4 AU). At that point it’ll be ripping along at ~68 km/s. Afterward, it passes 0.65 AU from Venus (Nov 3) and makes its closest approach to Earth on December 19 at ~1.8 AU—far, but perfect for

Siri on Instagram: "Full video link in bio 🔗 Mercury’s highly eccentric, egg-shaped orbit takes the planet as close as 29 million miles (47 million kilometers) and as far as 43 million miles (70 million kilometers) from the Sun. It speeds around the Sun every 88 days, traveling through space at nearly 29 miles (47 kilometers) per second, faster than any other planet. Mercury spins slowly on its axis and completes one rotation every 59 Earth days. But when Mercury is moving fastest in its ellipt
