what is the biggest asteroid in our solar system？
CeresAsteroids might look dry and barren, but the Solar System's biggest asteroid — Ceres — is chock full of water, NASA's Dawn spacecraft has found.2016年12月15日
Subsequently,What is the biggest asteroid ever found?
- Ceres1 - Ceres (583.7 miles / 939.4 kilometers) Ceres is the largest asteroid known to date.
In this regard,What is the largest asteroid near-Earth?
1036 GanymedThe largest known Near-Earth asteroid is 1036 Ganymed with a diameter of nearly 41 kilometers (25.5 miles). Scientists are working to identify Near-Earth asteroids with diameters of 1 kilometer (0.6 mile) or more that may pose a danger of colliding with the Earth.
Thereof,What asteroid will hit Earth?
On average, an asteroid the size of Apophis (370 metres) is expected to impact Earth once in about 80,000 years....99942 Apophis.

Long,What would happen if Vesta hit Earth?
After impacting the crust, Vesta would create something both Redditors and NASA scientists like to call a "crust tsunami." The Earth's crust would be peeled away from the point of impact, rolling up in a towering wave of material stretching out far beyond the upper atmosphere and into space itself.
ApophisExactly seven years from today—on April 13, 2029—the “Potentially Hazardous Asteroid” (PHA) called Apophis will pass inside the orbits of our geosynchronous satellites. That's about 23,000 miles/37,000 kilometers from Earth's surface. That's close. Apophis is enormous.
Ceres, Pallas, and Vesta are the three largest asteroids. Even though they are much smaller than the planets (Ceres, the largest asteroid, has only 1% the mass of the Moon), they are still capable of causing changes in the orbits of Mars and the Earth.
Some bad news from European mathematicians: there seems to be a significant chance that within the next 1.14 million years, an asteroid named 433 Eros could hit Earth, with dire results for the human race and most other species. Little 433 Eros is not on most lists of potential planetary catastrophes.
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
ApophisApophis is a space rock about 1,000 feet (340 meters) across. Calculations in recent years have proven the asteroid will safely glide past Earth in both 2029 and 2036.
around 12km wideThe asteroid that killed the dinosaurs Although NASA does not know where the asteroid originated from, we do know its size now. It was around 12km wide. The asteroid struck the Earth in the Gulf of Mexico's Yucatan Peninsula creating the 180-kilometer wide Chicxulub crater.
2017 PDC2017 PDC: The asteroid that will hit earth in 2027. According to the NASA Jet Propulsion Lab, asteroid 2017 PDC has a 96% chance of hitting earth in 2027. Even though the 2017 PDC Asteroid only has a diameter of between 100 meters and 250 meters, it could still cause devastating destruction.
Ultimately, scientists estimate that an asteroid would have to be about 96 km (60 miles) wide to completely and utterly wipe out life on our planet.
