99942 Apophis (/ ə ˈ p ɒ f ɪ s /, previously known by its provisional designation 2004 MN 4) is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a probability of up to 2.7% that it would hit Earth on April 13, 2029. But over the next few days, Apophis will come within only 15 million kilometres of Earth.

Orbit diagram of 99942 Apophis (credit: JPL). Label the following on your diagram: orbit, gravity, original velocity, aphelion, and perihelion. Introduction to NEO orbits: NEO Lookup: Use this tool to lookup a specified NEO in our database and display known orbital and physical parameters and optionally display an orbit diagram: NEO DB Query: Use this tool to find NEOs matching various user-specified orbital and physical constraints: Horizons The “Colossal God of Chaos” asteroid, 99942 Apophis, is somewhere in the vicinity of 2,132 feet in diameter, or 0.4 miles wide, and if it hit Earth on one of the 10 dates NASA has designated as having a “calculable risk of deadly impact” it would end humanity as we know it. The blue dots represent artificial satellites orbiting the Earth, and the purple ring shows the orbit of the International Space Station. Apophis is a small asteroid, only about 300 meters in diameter (approximately 1,000 feet).

3D and 2D ground tracks of trajectories of Apophis as the Earth rotates from April 01, 2028, to April 01, 2030. Additional observations revealed that Apophis will miss by a hair (passing closer to earth than our geosynchronous satellites), but its orbit will be changed by that close approach such that there is a small chance of an Earth impact on April 15, 2036. The orbit diagram of 2004 QY2 is shown in Figure 1. Below are orbit diagrams showing the trajectory of Asteroid 52768 (1998 OR2) and the path it will be taking which will see it, hopefully, pass by Earth without consequence next month. Depuis Novembre et jusqu’en Janvier 2013 on peut remarquer l’astéroïde Apophis dans une course poursuite à proximité de la Terre et s’éloigner ensuite progressivement.

C’est ce que l’on peut remarquer sur l’Orbit Diagram de la Nasa par une évaluation avec l’animation. The JPL Small-Body Database Browser provides data for all known asteroids and many comets. Friday the 13th of April 2029 could be a very unlucky day for planet Earth. Diagram showing the trajectory of the asteroid Apophis when it swings within 19,000 miles of Earth on April 13, 2029. From the simulations in Figure 7, we can see that 2004 QY2 . Draw a diagram of Earth orbiting the Sun. Visualization of Asteroid 99942 Apophis Orbit This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 99942 Apophis with … The orbit elements of Apophis before and after the impact are shown in Table 4. Discovery circumstances are updated on a roughly monthly interval.
