Now we are able to view the earth from space and understand that the solstice is an astronomical event which happens because of Earth’s tilt on its axis and movement around the sun

It is the tilt of Earth and not the distance from the sun which causes summer and winter.  Earth is tilted on its axis by 23.5°.  Our Northern and Southern hemispheres swap places in receiving the sun’s light and warmth.  At the moment of the December solstice, the Northern hemisphere is tilted furthest away from the sun.
Whatever you feel about the winter and the short days, you can begin to enjoy longer days from the 22nd.  The science and technical details of the solstice and Earth’s movements can be appreciated further on a number of websites – the one we found which explained it the most clearly is
