We’re fine in 2525 but I haven’t looked from like now until then 😂😂😂
🪐 Dangerous Asteroids Near Earth — Summary & Analysis (Updated 2025-10-11)
================================================== ⚠️ WHAT MAKES AN ASTEROID "DANGEROUS"
A Near-Earth Asteroid (NEA) becomes "potentially hazardous" if it: • Passes within 0.05 AU (~7.5 million km) of Earth. • Is larger than ~140 meters in diameter. • Has uncertain orbits that could shift due to gravitational effects.
Even smaller objects can cause airbursts (like the 2013 Chelyabinsk event).
================================================== 🧮 SIZE AND IMPACT ANALYSIS
| Name | Size (m) | Threat Level | Comment |
|---|---|---|---|
| 2007 EV | 59.4 | Moderate | Could cause local/regional damage if impact. |
| 2017 WK13 | 717.8 | Severe | Large enough for global or continental destruction if impact. |
| 2019 UL | 9.0 | Low | Would likely burn up in atmosphere; airburst possible. |
| 2020 BQ12 | 74.8 | Moderate | Could cause significant local damage. |
| 2020 PH5 | 199.5 | High | Approaches “potentially hazardous” threshold. |
| 2022 AL3 | 241.0 | High | Severe impact if collision occurred. |
| 2022 RJ1 | 29.6 | Low | Airburst-type event similar to Chelyabinsk. |
| 2022 SM10 | 79.8 | Moderate | City-scale destruction if impact. |
| 2023 LL1 | 13.5 | Low | Burns up in atmosphere. |
| 2023 UZ2 | 25.0 | Low | Airburst potential, unlikely to reach ground. |
| 2023 VT5 | 132.4 | High | Could cause massive local/regional effects. |
| 2024 JH | 44.5 | Moderate | Localized destruction if impact. |
| 2024 RM | 84.7 | Moderate | Significant local threat. |
| 2025 QL9 | 112.7 | High | On the edge of the “hazardous” category. |
| 2025 SU25 | 69.7 | Moderate | Local risk, depending on composition. |
| 2025 TQ1 | 66.7 | Moderate | Local danger if impact. |
| 2025 TS2 | 42.7 | Low | Minor local threat. |
================================================== 🌍 CONTEXT — MOST ARE SAFE
NASA’s Sentry and ESA’s NEODyS systems constantly track over 30,000 NEAs. None of these listed are projected to hit Earth in the next century. Most of them make routine flybys — often within a few lunar distances, but safely.
================================================== 💡 INTERPRETING SIZE AND ENERGY
Impact energy roughly scales as: E = 1/2 × mass × velocity²
An asteroid:
• 10 m across burns in the atmosphere.
• 50–100 m can devastate a city.
• 500 m–1 km affects continents.
• >1 km causes global climate impact.
================================================== 🛰️ PLANETARY DEFENSE PROGRAMS
• NASA’s Planetary Defense Coordination Office (PDCO) monitors these daily.
• NEOWISE and ATLAS telescopes scan the sky for new NEAs.
• DART Mission (2022) proved we can alter an asteroid’s orbit through kinetic impact.
================================================== 📜 TAKEAWAY
These asteroids are part of a living catalog — most pose no threat, but they remind us of Earth’s vulnerability and the need for continued space observation and defense funding.
