February 2023 News, research and Starcharts
Hi Everyone
A lot of interesting research papers out this month that caught my attention. Well it’s been a month of Weather extremes here in NZ and the tropics are still quite active to our north, and North America has been hit with some bad storms as well. Moving on to the highlights to read.
Looking at our own solar system there was a good study on how stable a super Earth Planet would be in our solar system between Mars and Jupiter and it’s probably a good thing we don’t have one present as it could cause some instabilities however A Earth mass planet wasn’t modelled or smaller Mars sized planets, these could be more stable. The search for a distant super Earth around our solar system turned up in an interesting paper this month. By carefully studying the positions of the known planets and some asteroids, the planet could well be detected however the problem was in gaining accurate information on the location of all the solar system objects.
Exo planets around Red dwarfs also has some interesting news out this month, from a Jupiter sized discovery and nearby Earth sized planets too.

I can remember attending an investment seminar or talk I my early 20s which must have been around the early 2000’s. The Speaker started off with Saying “Living in Australia and New Zealand you have already won the lottery, on this planet” it’s a quote I’ve always remembered, and thinking about a major volcanic eruption, asteroid strike or a nuclear war it sure seem relevant today.
