A meteoroid with a mass of 1190 kg is detected heading toward the Earth, which has a mass of 5.98×1024 kg. Its speed at a distance of 3.85×108 m from the center of the Earth (roughly the distance to the Moon), is 2000 m/s. Fortunately, it misses the Earth by a distance of 1.03×107 m, measured from the Earth's center. How fast was the meteoroid traveling when it came closest to the Earth? The effects of the Sun's and Moon's gravity can be ignored. (in m/s)

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

conduct current i mean it makes sense
