There is no such thing as asteroid showers, perhaps you mean meteor showers.
Asteroids can be seen through telescopes on any clear night, but you have to know where to look. They cannot be seen without a telescope.
Comet Swift-Tuttle
The Leonids meteor shower are associated with the comet Tempel-Tuttle.
When the Earth's orbit passes through the tail of a comet normally.
comet Tempel-Tuffle
Apart from things directly related to the comet, no. Since the comet has a regular orbit, it is possible to predict when it will be visible. Halley's Comet is also the cause of the Eta Aquariid meteor shower, so the passage of the comet may result in an increase in the shower's intensity. In most cases, trying to predict the future based on the positions of celestial objects falls under the field of astrology, which is a pseudoscience.
