Are dinosaurs still alive today?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period..

How far is the asteroid from Earth 2020?
The asteroid was discovered during its approach to Earth, and was at nominal distance of about 0.11 AU (16,000,000 km; 10,000,000 mi) from the planet. At the time of discovery, 2020 BX12 was located in the constellation of Puppis at an apparent magnitude of 17.6.
How would NASA stop an asteroid?
An object with a high mass close to the Earth could be sent out into a collision course with the asteroid, knocking it off course. When the asteroid is still far from the Earth, a means of deflecting the asteroid is to directly alter its momentum by colliding a spacecraft with the asteroid.
What will happen in 2020?

What if the dinosaurs never went extinct?
“If dinosaurs didn’t go extinct, mammals probably would’ve remained in the shadows, as they had been for over a hundred million years,” says Brusatte. “Humans, then, probably would’ve never been here.” … Gulick suggests the asteroid may have caused less of an extinction had it hit a different part of the planet.
What if the asteroid that killed the dinosaurs missed?
Without the asteroid strike, the dinosaurs probably would have continued evolving into new and varied forms as climates changed. One evolutionary path might have led to a reptile with grasping hands and a large brain, filling the niche in which we humans have evolved.
Which asteroid will hit Earth?
As of October 2019, there were two asteroids with a more notable cumulative Palermo Technical Impact Hazard Scale than Apophis, though none of them have a Torino level greater than 0. On average, an asteroid the size of Apophis (370 metres) can be expected to impact Earth once in about 80,000 years.
What comets will be visible in 2020?
Comet C/2020 F8 (SWAN) is now visible with good binoculars in Northern Hemisphere skies, too, although finding it requires skill, with only a small window for locating it each day. That’s because the comet is rising only shortly before the sun, and can be found near the horizon when dawn breaks.
When did the last asteroid hit Earth?
66 million years agoThe last known impact of an object of 10 km (6 mi) or more in diameter was at the Cretaceous–Paleogene extinction event 66 million years ago. The energy released by an impactor depends on diameter, density, velocity, and angle.
Which asteroid is coming towards Earth in 2020?
The asteroid was discovered during its approach to Earth of 0.02915 AU (4.361 million km; 11.34 LD)….2020 BX. 12.2020 BX12 and its satellite imaged by the Arecibo Observatory in February 2020DiscoveryDiscovered byATLAS-MLODiscovery siteMauna Loa Obs.28 more rows
What will happen when an asteroid hits the earth?
It’s because if a large-enough asteroid explodes in the air before hitting the Earth (and generating tsunamis, craters, and fire-filled torrents of death), the resulting shockwave could blast winds powerful enough to flatten cities. The pressure from the blast could rupture internal organs.
Where did the last asteroid hit Earth?
It was formed when a large asteroid or comet about 11 to 81 kilometers (6.8 to 50.3 miles) in diameter, known as the Chicxulub impactor, struck the Earth….Chicxulub crater.Impact crater/structureCountryMexicoStateYucatánChicxulub crater Location of Chicxulub crater Show map of North America Show map of Mexico Show all12 more rows
How big was asteroid that killed dinosaurs?
It was formed when a large asteroid or comet about 11 to 81 kilometers (6.8 to 50.3 miles) in diameter, known as the Chicxulub impactor, struck the Earth.
What would happen if asteroid hit ocean?
When an asteroid hits the ocean, it’s more likely to produce storm-surge-sized waves than giant walls of watery death. That’s the preliminary result of an experiment that used paintballs to help clear up some of the confusion around what happens when a space rock splashes into the ocean.
