Conversely, young trails are spatially very dense and the cause of meteor outbursts when the Earth enters one. In the case of the Leonids, that tends to peak around 18 November, but some are spread through several days on either side and the specific peak changes every year. Old trails are spatially not dense and compose the meteor shower with a few meteors per minute. These trails of meteoroids cause meteor showers when Earth encounters them. They are differentially disturbed by the planets, in particular Jupiter, and to a lesser extent by radiation pressure from the Sun – the Poynting–Robertson effect and the Yarkovsky effect. The meteoroids left by the comet are organized in trails in orbits similar to – though different from – that of the comet. An annual Leonid shower may deposit 12 or 13 tons of particles across the entire planet. Larger Leonids which are about 10 mm (0.4 in) across have a mass of 0.5 g (0.02 oz) and are known for generating bright ( apparent magnitude −1.5) meteors. Due to the retrograde orbit of 55P/Tempel–Tuttle, the Leonids are fast moving streams which encounter the path of Earth and impact at 70 km/s (43 mi/s). The streams consist of solid particles, known as meteoroids, normally ejected by the comet as its frozen gases evaporate under the heat of the Sun when it is near the Sun – typically closer than Jupiter's orbit. Įarth moves through meteoroid streams left from passages of a comet. The meteor shower peak should be on 17 November, but any outburst in 2023 is likely to be from the 1767 meteoroid stream. Their proper Greek name should be Leon tids ( Λεοντίδαι, Leontídai), but the word was initially constructed as a Greek/ Latin hybrid and it has been used since. The Leonids get their name from the location of their radiant in the constellation Leo: the meteors appear to radiate from that point in the sky. The Leonids ( / ˈ l iː ən ɪ d z/ LEE-ə-nidz) are a prolific annual meteor shower associated with the comet Tempel–Tuttle, and are also known for their spectacular meteor storms that occur about every 33 years.
