Bee Hotels for Solitary Bees

You may be wondering what bees need a hotel for, when they make their own hives. The truth is that many species of bees are solitary – the do not live in hives but instead construct their own nest. The main reason for this is because in these species every female is fertile and this would not make for comfortable communal living in a hive.

Perihelion and Aphelion

The closest point to the Sun in a planet’s orbit is called Perihelion. The furthest point is called Aphelion. The planet moves fastest at perihelion and slowest at aphelion.

Planets in our Solar System orbit the Sun. The orbits of some planets are almost perfect circles, but others are not. Some orbits are shaped more like ovals, or “stretched out” circles.

Scientists call these oval shapes “ellipses”. If a planet’s orbit is a circle, the Sun is at the center of that circle. If, instead, the orbit is an ellipse, the Sun is at a point called the “focus” of the ellipse, which is not quite the same as the center.

Since the Sun is not at the center of an elliptical orbit, the planet moves closer towards and further away from the Sun as it orbits. The place where the planet is closest to the Sun is called perihelion.

When the planet is furthest away from the Sun, it is at aphelion. The words aphelion and perihelion come from the Greek language. In Greek, “helios” mean Sun, “peri” means near, and “apo” means away from.
