I need to know where the one on my planet is.

If you click on the planet button when you are in the travel pane you will see the planet terrain layouts including where the cities are. You will just need to look for a city with a slightly different icon -

If you move the mouse over it you will see a tooltip which says NPC transport available. That is the city with the starport allowing you to move between planets.

Be warned however that the cost of transport is normally beyond the means of a starting player so you may prefer to join a faction and hopefully get them to pay for your journey to get to them.

Okay thank you. Yea my faction is going to transport me I just have to find the spaceport to meet them

I cant tell from the planet map. Has anyone been to tellus before?

It doesnt have a starport on the map. Somebody will have to physically come and get you.

Thats what I just realized. Can freighters land in cities or do I need to get out of the town

They can land on every free ground square.
