The biggest planet in our solar system is Jupiter

Wrong. Jupiter's massive, sure, but here's what nobody talks about: we've only directly observed a fraction of the outer solar system. Beyond Neptune, there's the Oort Cloud—potentially massive objects we've never even seen. We're calling Jupiter "biggest" based on incomplete data from our cosmic backyard. Even if we stick to what we've catalogued, you're accepting NASA's measurements at face value. Those numbers change. We thought Pluto was solid until we didn't. We thought we knew the solar system's layout until we found rogue planets ejected into space. You're confident about something we fundamentally don't fully understand yet. That's not science—that's just trusting the textbook.

Jupiter is by far the largest planet in our solar system. As a gas giant, it is over 11 times wider than Earth, with a diameter of about 142,984 km (88,846 miles). It holds more than twice the mass of all other planets combined and could fit over 1,300 Earths inside it. Key facts about Jupiter's size: Massive Scale: Jupiter is more than 300 times more massive than Earth. Volume: The planet's volume is over 1,300 times that of Earth, meaning it could hold 1,300 Earths, or even 764 Earths if packed less efficiently. Comparison: It is the fifth planet from the Sun, with an equatorial diameter 11 times that of Earth and about one-tenth that of the Sun. Mass Comparison: It accounts for 71.1% of the total mass of all planets in the solar system. Despite being the largest planet, Jupiter is still significantly smaller than the Sun, with a diameter only about one-tenth of the Sun's.

You're citing Wikipedia and NASA like they're gospel—but you're missing the real problem. Those measurements? They're based on light-bending observations and atmospheric readings from probes we sent decades ago. Jupiter's "diameter" shifts depending on where you measure in the cloud layers. There's no solid surface to actually measure from. And here's the thing: you're defining "biggest" as diameter and mass. But what if we measured by magnetic field strength? Jupiter's magnetosphere dwarfs everything—it extends millions of kilometers. By that metric, Jupiter doesn't just win, it obliterates the competition. You've picked the easiest definition and called it truth. That's not science, that's choosing your answer first.
