On the night of the peak, astronomers expect anywhere between 15 to 30 meteors an hour.
According to the US space agency NASA, the meteors crash into our atmosphere at speeds about 148,000mph.
The meteors appear to arrive from the constellation Orion, hence their name, and are visible in the Northern and Southern Hemisphere.
NASA said: “Fast meteors can also sometimes become fireballs: look for prolonged explosions of light when viewing the Orionid meteor shower.
“The Orionids are also framed by some of the brightest stars in the night sky, which lend a spectacular backdrop for these showy meteors.”
