Comets are a mixture of ice and dust that failed to come together as a planet. Sometimes they are called dirty snowballs. Their tails point away from the sun at all times, so when a comet is moving away from the sun, its tail is actually leading. Comet tails are caused by dust and gas being lost from the comet and then pushed away from the sun by the solar wind, charged particles moving out from the sun, and by radiation pressure from the sun.
The sun is the largest object in our solar system. More than 1 million Earths could fit inside the sun.
A space shuttle's main engine weighs about a seventh as much as a train engine but can deliver as much horsepower as 39 train engines.
